Answer:

y = 3x + 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (- 2, - 2) ← 2 points on the line

m = [tex]\frac{-2-4}{-2-0}[/tex] = [tex]\frac{-6}{-2}[/tex] = 3

the line crosses the y- axis at (0, 4 ) ⇒ c = 4

y = 3x + 4 ← equation of line

Answer:

y=3x+4

Step-by-step explanation:

The formula used is point slope, or y=mx+b

here, the m is the slope, and the b is the y-intercept

The y-intercept is where the graph crosses the y-axis, also known as when x=0

In this case, the y intercept is at the point (0,4) so you'd plug in 4 for the 'b' in the equation

To find the slope, use the rise over the run of the graph.

To do this, pick two points along the graph, and count how many units up/down, and to the left/right between the two points

The units up/down goes on top, being positive if they're up, and negative if they're down

The units left/right go on bottom, being positive if they're right, and negative if they're left

In this case you go 3 units up, and 1 unit right, so the slope would be 3/1 or 3

A printer takes seconds to print a lyer. It took 75 seconds to print a batch of lyers without stopping. How many lyers were in the batch?

Answers

If it takes a printer seconds to print a single lyer, and it took 75 seconds to print a batch of lyers without stopping, the number of lyers in the batch is 75 / . This is because if it takes seconds to print a lyer, and we have 75 seconds available to print lyers, we can divide the total time available by the time it takes to print each lyer to find out how many lyers we can print.

For example, if it takes 3 seconds to print a single lyer, the number of lyers in the batch is 75 / 3 = 25. If it takes 2 seconds to print a single lyer, the number of lyers in the batch is 75 / 2 = 37.5.

Therefore, the number of lyers in the batch depends on the time it takes to print a single lyer. To find the exact number of lyers in the batch, we need to know the time it takes to print a single lyer.

This can be determined by using the property of exponents that states that x^n * x^m = x^(n+m). In this case, 10^n * 10^5 = 14,521, so 10^(n+5) = 14,521. Solving for n, we get n = 5.

Seth is comparing scenarios to determine which starting point he should get dropped off at to get him to school faster. Seth's house is 17 miles from school. In which scenario does seth start closer to school? in which scenario does seth travel at a greater speed, and what was the rate?.

Answers

In  linear equation, He travels at a greater speed from his friend's house, at a rate of 0.6667 miles per minute, that is, 2 miles in 3 minutes.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.  

                             Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Using linear function concepts, it is found that:

Seth starts closer to the school in the bus.

He travels at a greater speed from his friend's house, at a rate of 0.6667 miles per minute, that is, 2 miles in 3 minutes.

From the graph of the bus, when he takes the bus, he is 13 miles from the school, as he starts at position 4 and ends at 17.

At his friend house, he is 13 miles from the school only after 3 minutes, which means that the bus will be closer.

The scenario with the greater speed is the one with the higher slope, that is, higher rate of change, which is the change in distance divided by the change in time.

In the bus, change of 13 miles in 24 minutes, thus

       mᵇ = 13/24 = 0.5417

   From the friend's house, change of 2 miles in 3 minutes, thus

   mf = 2/3 = 0.6667

Thus, he travels at a greater speed from his friend's house, at a rate of 0.6667 miles per minute, that is, 2 miles in 3 minutes.

The weights for 12-month-old baby boys are normally distributed with a mean of 22.5 pounds and a standard deviation of 2.2 pounds.

Find the percentage to the nearest tenth of 12-month-old baby boys who weigh between 19.7 and 24.4 pounds.

ANSWER -

Answers

Answer:

70.5%

Step-by-step explanation:

If a continuous random variable X is normally distributed with mean μ and variance σ², it is written as:

[tex]\large\boxed{X \sim\text{N}(\mu,\sigma^2)}[/tex]

Given:

Mean μ = 22.5Standard deviation σ = 2.2

Therefore, if the weights of the 12-month-old baby boys are normally distributed:

[tex]\boxed{X \sim\text{N} \left(22.5,2.2^2 \right)}[/tex]

where X is the weight of the baby boy.

To find the percentage to the nearest tenth of 12-month-old baby boys who weigh between 19.7 and 24.4 pounds find P(19.7 ≤ X ≤ 24.4).

Calculator input for "normal cumulative distribution function (cdf)":

Upper bound: x = 19.7Lower bound: x = 24.4σ = 2.2μ = 22.5

[tex]\implies \text{P}(19.7 \leq X \leq 24.4)=0.704548741[/tex]

[tex]\implies \text{P}(19.7 \leq X \leq 24.4)=70.5\%[/tex]

Therefore, the percentage of 12-month-old baby boys who weigh between 19.7 and 24.4 pounds is 70.5% (nearest tenth).

Suppose that 6 < x < 7 and 10 < y < 12. Find all possible values of each expression.

y - x

Answers

Answer:     3 < y-x < 6

The set of all possible y-x values is between 3 and 6, excluding both endpoints.

===================================================

Explanation:

The y-x value is smallest when:

The y value is as small as possibleThe x value is as large as possible

I recommend to draw out a number line. The idea is to place x and y as close as possible to each other.

Based on those two conditions, we use y = 10 and x = 7 respectively. That gives y-x = 10-7 = 3 as the smallest possible difference. Keep in mind we can't actually reach this value so we would write y-x > 3 which is the same as 3 < y-x.

--------------------

Similarly, y-x is largest when:

The y value is largestThe x value is smallest

Like earlier, use a number line to see why this would be the case. We're trying to space x and y out as far as possible.

The largest y value and smallest x value are y = 12 and x = 6 in that order. So the upper bound is y-x = 12-6 = 6. Like before, we can't actually reach this number which means we write y-x < 6.

--------------------

Recap:

In the 1st section, we found that 3 < y-xIn the 2nd section, we found that y-x < 6

Put those two results together in a tidy compound inequality to get the final answer    3 < y-x < 6

It says: The expression y-x is between 3 and 6, excluding both endpoints.

The value that Helen wants to use is Pi = C/D. The lower bound value is 3.065, and the upper bound for Helen's value is 3.165.

What is circumference?

The circumference is the perimeter of the circle.

Given, the circumference, C, at 405 mm to three significant numbers.

She correctly estimates the diameter, d, to be 130 mm to two significant numbers.

Helen wants to find the value of Pi using the formula pi=C/D

We have, the circumference of the circle = C = 405 mm

The diameter of the circle = d = 130 mm

Pi = C/D

= 405 mm / 130 mm

= 405 / 130

= 3.115

3.115, measured to the nearest 0.1.

The degree of accuracy is nearest 0.1.

0.1/2 = 0.05

Upper bound = 3.115 + 0.05 = 3.165

Lower bound = 3.115 - 0.05 = 3.065

Therefore, the lower bound and upper bound for Helen's value are 3.165, and 3.065.

The original triangle⬇️

Answers

The properties of the triangles created from the original triangle based on triangle congruency rules are as follows;

SSS: The triangle created using the lengths of the three sides of the original should have the same length and angles as the original

The triangle formed using SSS is a unique triangle and no other triangle has similar dimensions

SAS: The lengths of the sides and the measure of the angles should be the same

The triangle created using SAS is a unique triangle and there is not a way to have a third side that has a different length

ASA; The triangle formed using the ASA of the original triangle should have the same length as the same lengths and angles as the original triangle

The triangle formed using ASA is a unique triangle and there is not a way to create a triangle that has a different side length.

What are congruent triangles?

Two triangles are congruent if the lengths of the three sides of one triangle are congruent to the three sides of the other triangle or if they meet the other conditions of triangle congruency.

Length of first measured side of the triangle = 52 units

Angle made by the first measured side with the horizontal = 41°

Length of the second measured side of the triangle = 87 units

Angle the second measured side makes with the horizontal = 33°

Length of the third measured side of the triangle = 113 units

Angle the third side makes with the horizontal ≈ 6.5°

Let the vertices of the first side be A and B, we get;

∠A = 180° - (41° + 33°) = 106°

∠C = 33° - 6.5° = 26.5°

∠B = 41° + 6.5° = 47.5°

SSS: The SSS (Side-Side-Side) congruency postulate states that if the three sides of one triangle are congruent to the three sides of another triangle, then the two triangles are congruent.

Therefore, the lengths of the sides and the measures of the angles of the triangle created using the lengths of the three sides of the original triangle will be the same as the original triangle.

The SSS congruency postulate indicates that the triangle created using the same lengths of the three sides of the original triangle is a unique triangle and there are no other triangles having the same side lengths but different angles

SAS: The Side-Angle-Side, SAS, congruency postulate states that if the adjacent sides and an included angle of a triangle are congruent to two adjacent sides and an included angle of another triangle, then the two triangles are congruent.

Therefore, the triangle formed using two sides of the original triangle and the included angle between them will have the same length as the sides of the original triangle, and the triangle formed using the SAS of the original triangle is unique

The length of the third side of the triangle created using the SAS measurement is always the same as the length on the original triangle

ASA: The Angle-Side-Angle, ASA, congruency postulate states that if two angles and the included side of one triangle are congruent to two angles and an included side of another triangle, then the two triangles are congruent.

The triangle formed using the ASA is a unique triangles and therefore and there is no way to create a triangle that has a different side length

y-intercept means that the number of vehicle-miles traveled in 1975 is; 1.345 (in trillions)

A reasonable prediction for the number of miles people in the U.S. will travel in 2022 is; 3.601 (in trillions)

How to interpret the equation of line of best fit?

The equation for the line of best fit is given as;

y = 0.048x + 1.345

where;

x is the number of years since 1975

y is the number of vehicle-miles traveled in trillions

The equation of a line in slope intercept form has the general form as;

c is y-intercept

Thus;

Slope = 0.048 which is the rate at which the number of miles people in the U.S. traveled per year increases.

y-intercept = 1.345 (in trillions) which is the number of vehicle-miles traveled in 1975

The year 2022 will be 47 years since 1975 and so the prediction is;

Tyler was trying to prove that all rhombuses are similar. He thought, "If I draw 2 rhombuses. I can find dilations that will take one rhombus exactly onto the other." Then he wrote a proof.
All rhombuses are not similar. Which steps in Tyler's proof have flaws? Explain what is wrong with each step that is wrong.

Step 2: Dilate rhombus ABC D by the scale factor given by
WX
4B Side A'B' will be the same length as W X because of how I chose the scale factor. Because all sides ofa
thombus are congruent, B'C' will be the same length as W X and therefore the same length as XY, C'D' will be the same length as Y Z, and A'D' will be the same length as W Z. That means all the corresponding sides of A' B'C'D and W XY Z will be the same length.
Step 3: If all the sides in 2 figures are proportional, then those 2 figures are similar, so there must be a sequence of transformations that take ABC D onto W XYZ using dilations and rigid motions.
Step 4: Translate A' B'C'D' by the directed line segment A'W so that A" and W coincide.
Step 5: Rotate A" B"C" D" by angle B"W X so that B/' and X coincide. Now segments A' B'' and WX coincide.
Step 6: If needed, reflect A" B''O' D'' over segment W X so that D'' and Z are on the same side of WIX. Now segments A"' D' and WZ coincide.

Yes, the lines are parallel. This is because the lines have the same slope. The slope of a line is a measure of how steep the line is, and it is calculated by taking the difference of the y-coordinates of two points on the line and dividing it by the difference of the x-coordinates of the same two points. In this case, the slope of line a is -1, and the slope of line b is also -1. Because the lines have the same slope, they are parallel to each other.

what is an equation of the line that passes through the points (8,-3) and (4,2)

Answers

Answer:

y = –5x/4 + 7

Step-by-step explanation:

x1 = 8 ,x2 = 4, y1 = –3 , y2 = 2

lets find the slope(m)

m = y2–y1/x2–x1

m = 2 – (–3)/ 4 – 8

m = 5/ –4

m= –5/4

to find the equation of a line using this as our guider y = mx + b

we will make use of one coordinate

(8,–3)

using the formula for one point

y – y1 = m(x – x1)

y – (–3) = –5/4(x – 8)

y + 3 = –5x/4 + 10

y = –5x/4 + 10 –3

y = –5x/4 + 7

The basketball team scored a total of 109 points last game. They made a total of 47 shots, including 2-point shots and 3-point shots. how many 2-point shots did they make? How many 3-points did they make?
[please include steps]

Answers

Based on the above, the number of 3-points that they make is 25.

What is the Simultaneous equation about?

Simultaneous equation is a form of two equations that have to be solved at the same time. Thus, the number of 2 points made is 17, while that of 3 points is 25.

A set of equations that has to be solved simultaneously so as to determine the values of the unknown variables is termed simultaneous equation.

The given question would result to a simultaneous equation as follows;

let the number of 2 points made by represented by m, and that of 3 points by n.So that;

m + n = 42  ..................

i2m + 3n = 109  ...............

ii multiply equation 1 by 3 and equation 2 by 1 to have;3m + 3n = 126 ............

iii 2m + 3n = 109 .............

iv subtract eqaution iv from iii

m = 17

substitute the value of m in equation 1 to have:

m + n = 4217 + n = 42n = 42 - 17   = 25m = 17, n = 25

Thus the number of 2 points made was 17, while that of 3 points made was 25.

The median of a boulevard i 8 feet wide and 300 feet long. What i the area of the median?

Answers

By using the formula for area of rectangle, it can be calculated that Area of the median is 2400 sq. feet

What is area of rectangle?

The area of a rectangle is calculated by multiplying the length by the width. For example, if a rectangle has a length of 10 feet and a width of 6 feet, the area would be 10 x 6 = 60 square feet. The area of a rectangle is a two-dimensional measurement and is typically expressed in units squared, such as square feet or meters squared. Other shapes, such as a triangle or a circle, also have areas and are calculated differently.

If l is the length of the rectangle and b is the breadth of the rectangle, then area of rectangle is calculated by the formula

Area = [tex]l \times b[/tex]

Length of the median = 300 feet

Width of the median = 8 feet

Area of the median = 300 [tex]\times[/tex] 8 = 2400 sq. feet

The length of second lawn is found as the 36 sq. m.

Explain the term area of the rectangle?The area a rectangle occupies is the space it takes up inside the limitations of its four sides. The dimensions of a rectangle determine its area.In essence, the area of a rectangle is equal to the sum of its length and breadth.

For the stated question-

First lawn:

Length  = 6 mWidth = 4 m

Area = length x width

A = 6 x 4 = 24 sq. m.

Second lawn:

Length = LWidth = 4 mArea A2 = 6 x Area of first lawn

A2 = length x width

6 x A = L x 4

6 x 24 = L x 4

L = 6 x 6

L = 36 sq. m

Thus, the length of the second lawn is found as the 36 sq. m.
