Answer 1

Answer:

Step-by-step explanation:

Subtract -4x on both sides to get to -2y=-4x-8, then you should divide -2 into both sides to get to the slope of y=2x+4 since two negatives would equal to a positive when dividing and multiplying. Because the slope is positive, it is safe to assume that the first two options A and B are the best options due to their slopes being positive and going up. The y-intercept is 4 which makes the answer A because on 0 it is on the positive side.

Rachel can walk 2.5 miles in 40 minutes at this rate how far can she walk in one hour

Answers

My answer~

3.75 miles

Explination~first you would start by finding out how many miles she walks in 1 minute by dividing 2.5 by 40

2,5 ÷ 40 =

0.0625

Then you would times that by 60, because 60 minutes equals 1 hour

0.0625 × 60 =

3.75

So, Rachel can walk 3.75 miles in 1 hour :))------------------------------------------------------------------------

6y=3y-18 What is thee slope intercept and what is the slope

Answers

Answer:

y = (1/2)x - 3

The slope is m = 1/2 and the y-intercept is (0, -3).

Step-by-step explanation:

Assuming that you meant 6y = 3x - 18, we solve this equation for y to obtain the slope-intercept formula y = mx + b for this particular case:

y = (3/6)x - (18/6), or

y = (1/2)x - 3

The slope is m = 1/2 and the y-intercept is (0, -3).

Find the sum of 5x+20 and the opposite.write an equivalent expression in standard form justify each step

Answers

Answer:

Therefore, the sum of 5x+20 and the opposite is: 0Thus, the equivalent expression is:

[tex]5x+20-\left(5x+20\right)=0[/tex]

Step-by-step explanation:

We know that the opposite is the additive inverse. For example, 8+(−8)=0 where 0 is the identity for addition.

Given that we have to compute the sum of 5x+20 and the opposite.

Given

5x+20opposite of 5x+20 = -(5x+20)

The sum of 5x+20 and the opposite:

5x+20 + -(5x+20)

Distribute the Negative Sign

[tex]=5x+20+-1\left(5x+20\right)[/tex]

[tex]=5x+20+-1\left(5x\right)+\left(-1\right)\left(20\right)[/tex]

[tex]=5x+20+-5x+-20[/tex]

Combine Like Terms

[tex]=5x+20+-5x+-20[/tex]

[tex]=\left(5x+-5x\right)+\left(20+-20\right)[/tex]

[tex]=0+0[/tex]

[tex]=0[/tex]

Therefore, the sum of 5x+20 and the opposite is: 0Thus, the equivalent expression is:

[tex]5x+20-\left(5x+20\right)=0[/tex]

The original Volkswagen Beetle follows
a quadratic curve, write an equation if
the height is 5 feet long and the length
is 14 feet long. Show your work in the
sketchpads below.

Answers

Answer:

[tex]y= -\frac{5}{49}x^{2}+5[/tex]

Step-by-step explanation:

In order to solve this, we need to start by drawing a sketch of what the problem looks like (see attached picture).

From the picture, we can see that the graph of the equation should be a parabola with a vertex located at the point (0,5) and x-intercepts located at (-7,0) and (7,0) respectively.

So, there are two ways in which we can build a quadratic equation:

Standard form:

[tex]y=ax^{2}+bx+c[/tex]

Vertex form:

[tex]y=a(x-h)^{2}+k[/tex]

Since we already have the vertex and two points on the equation, we can directly use the vertex form. Where vertex is located at the coordinates (h,k)

So in this case: h=0 and k=5, which simplifies our equation a lot:

[tex]y=a(x-0)^{2}+5[/tex]

[tex]y= ax^{2}+5[/tex]

So we only need to find the value of a for our equation to be complete. We can use either x-intercept to find this. Let's use the point (7,0) so we get:

[tex]0=a(7)^2+5[/tex]

and now we can solve for a:

[tex]-5=49a[/tex]

[tex]a=-\frac{5}{49}[/tex]

so this completes our equation:

[tex]y= -\frac{5}{49}x^{2}+5[/tex]

whose graph looks like the one in the attached picture.

Simplify the following polynomial expression (8x^2-7x+2)+(3x^2-9x-6) help fasttt!!!!!!!!!!!!!

11x^2 - 16x +4

Step-by-step explanation:

In order to simplify, add like terms

(8x^2-7x+2)+(3x^2-9x-6)

8x^2 + 3x^2 = 11x^2

-7x + -9x = -16x

-6 + 2 = 4

Step-by-step explanation:

The measurement of ∠ B = 74°

What are Supplementary angles?

Two Angles are Supplementary when they add up to 180 degrees.

Given that ∠ A and ∠ B are Supplementary and ∠ A = (3x−23),

∠ B = (2x−12)

According to definition of Supplementary,

∠ A + ∠ B = 180°

(3x−23) + (2x−12) = 180°

5x - 35 = 180°

5x = 180° + 35

5x = 215°

x = 43°

Putting x = 43° in ∠ B = (2x−12)

∠ B = (2*43−12)

∠ B = 86 - 12

∠ B = 74°

Hence, The measurement of ∠ B = 74°

Graph the line
y = - 4/3x + 3

I need help with the steps.

Answers

Start by putting a dot at (0,3). Then you just need to go four down and three right from that dot and put another dot. Just repeat that a couple times to make sure it is straight, and connect the dots with a line. You can also go four up and three left from the (0,3) for the other side of the axis.

Step-by-step explanation:

First look at the y-intercept or b (in this case it is 3)

The y-intercept tells us where the line touches in the graph on the Y-axis

(In this case you move up in the Y-axis 3 times)

Put a dot on 3 (in the y-axis)

Now from 3 on the y-axis go down -4 and right 3 since the slope is -4/3

(Slope = rise/run -4 is rise [but since it the 4 is a -4 you go down] and 3 is run)

every time you finish going down -4 and right 3 place a dot on it and repeat if you think you can draw a line then stop and draw the line and you are finished

Which of the following represents the greatest percent of change?

A. Boots that were originally priced at $90 are on sale for $63
B. A baby that weighed 7 pounds at birth now weighs 10 pounds
C. A bracelet that costs $12 to make is sold for $28
D. A savings account increased from $500 to $600 in one year

Answers

Answer:

Step-by-step explanation:

a. 63(new) - 90(old) = -27 / 90 = 0.4285*100 = 42.9%

b. 10(new) - 7(old) = 3 / 7 = -0.3*100 = -30 = 30%

c. 28(new) - 12(old) = 14 / 12 = 1.166 * 100 = 116.6%

d. 600(new) - 500(old) = 100 / 500 = 0.2 = 20%

The greatest percentage change will be a bracelet that costs $12 to make and is sold for $28 as 133.33% thus option (C) is correct.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

% change = (change)/original x 100

A): (90 - 63)/90 x 100 = 30%

B): (10 - 7)/10 x 100 = 30%

C); (28 - 12)/12 x 100 = 133.33%

D):(600 - 500)/500 x 100 = 20%

Hence "The greatest percentage change will be a bracelet that costs $12 to make and is sold for $28 as 133.33%".
