Answers

Answer 1

Step-by-step explanation:

Your slope and your x and y intercept.

x + 2y =7

Divide through by 2, we have:

x/2 + 2y/2 = 7/2

x/2 + y = 7/2

y = 7/2 - x/2

In the form y = mx + c gives.

Where m is the slope.

There are 110 calories per 177.4 grams of Cereal X. Find how many calories are in 246.5 grams of this cereal.

Answers

The amount of calories in 246.5 gm of Cereal 397.5372 calories

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example,

Ram spends 36 Rs. for a dozen (12) bananas. 12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees. As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas. This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

In 177.4 gm of cereal contain 110 calories.

So, 1 gram cereal contain

= 177.4 / 110

= 1.6127

and, 246.5 gm will contain

=246.5 x 1.6127

= 397.5372 calories.

Hence, 397.5372 calories are in 246.5 grams of this cereal.

How to solve for 27-30 (X, Y, Z, and W)

27)

Opposite angles are equal.

x° angle is the opposite angle of the 90° angle.

Therefore, x°=90°.

28)

The 90° angle marked in the figure and the y° angles forms a linear pair.

Hence, both angles are supplementary. Supplementary angles sum upto 180°.

Therefore, we can write

[tex]\begin{gathered} y\degree+90\degree=180\degree \\ y\degree=180\degree-90\degree \\ y\degree=90\degree \end{gathered}[/tex]

Therefore, y°=90°.

In the figure, let z°+46°=p°.

From figure, we can see that the p° angle is the opposite angle of y° angle.

Since opposite angles are equal, we can write

[tex]\begin{gathered} p\degree=y\degree \\ z\degree+46\degree=y\degree \end{gathered}[/tex]

Since from part 28, y°=90°, we get

[tex]\begin{gathered} z\degree+46\degree=90\degree \\ z\degree=90\degree-46\degree \\ z\degree=44\degree \end{gathered}[/tex]

Therefore, zh=44e.

From figure,

one number is six less than a second number. Twice the first is 2 more than 4 times the second. Find the numbers

Answers

The two numbers are 11, and 5 if the one number is six less than a second number.

What is the number?

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

It is given that:

One number is six less than a second number.

Let the number be x and y:

x - 6 =  y

Twice the first is 2 more than 4 times a second.

2x = 2 + 4y

After solving the two linear equations:

2x = 2 + 4(x - 6)

2x = 2 + 4x - 24

2x = 22

x = 11

y = 5

Thus, the two numbers are 11, and 5 if the one number is six less than a second number.

○ x=85,y=38,z=63
○ x=80,y=48,z=63

Answers

Answer:

  (b)  x=80, y=38, z=63

Step-by-step explanation:

You want to know the values of x, y, and z, given they are angle measures in a diagram showing two triangles.

Linear pair

The angles that form a linear pair are supplementary:

  x° +100° = 180°

  x = 80 . . . . . . . . . divide by °, subtract 100

Angle sum theorem

The angle sum theorem tells you that the sum of angles in a triangle is 180°.

  y° +62° +80° = 180°

  y = 38 . . . . . . . . . . . . divide by °, subtract 142

In the other triangle, the same relation holds:

  z° +100° +17° = 180°

  z = 63 . . . . . . . . . . . . divide by °, subtract 117

The values of x, y, and z are ...

  (x, y, z) = (80, 38, 63)

What is the slope of the line that passes through the points (10, 4)(10,4) and (7, 3)(7,3)? Write your answer in simplest form.

Answers

The slope of the line that passes through points (10,4) and (7, 3) is 1/3

Here we are dealing with a slope of a line where a slope of a line is the change in the y coordinate with regard to the change in the x coordinate. If P(x1,y1) and Q(x2,y2) are the two points on a straight line, at that point the slope formula is given by:

m = Change in y-coordinates/Change in x-coordinates

m = (y₂– y₁)/(x₂ – x₁)

Since we are given two points (10,4) and (7, 3),  where x₁ and x₂ are 10, 7 whereas y₁ and y₂ are 4, 3

From  the formula we get,

m = (y₂-y₁)/(x₂-x₁)

Find a with the given information.
m=-6/7 (-10,0) and (a,-6)

Answers

By using the equation to find the slope, we will see that the value of a is -3.

How to find the value of a?

Here we have two points that define a line.

Remember that a linear equation is of the form:

y = m*x + b

Where m is the slope.

And we know that if the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:

m = (y₂ -  y₁)/(x₂ - x₁)

In this case, we know that the points are:

(-10, 0) and (a, -6), and the slope is m = -6/7, then we can write the equation:

-6/7 = (-6 - 0)/(a + 10) = -6/(a + 10)

The denominator should be the same in both sides, so we must have:

a + 10 = 7

a = 7 - 10 = -3

Then the two points are (-10, 0) and (-3, -6).

what’s the inverse of Y equals X squared -10 X

Answers

The inverse of the function y equals x squared - 10x (y = x² - 10x) is 5 ±√(x + 25).

What is an inverse function?

An inverse function simply refers to a type of function that is obtained by reversing the mathematical operation in a given function (f(x)).

First of all, we would translate the given word sentence into a function as follows:

y equals x squared - 10x  ⇒ y = x² - 10x

In order to determine the inverse of this function f(x) = x² - 10x, we would interchange both the input value (x) and output value (y) as follows:

y = x² - 10x

x = y² - 10y

Next, we would add (half the coefficient of the y-term)² to both sides of the function as follows:

x + (-10/2)² = y² - 10y + (-10/2)²

x + 25  = y² - 10y + 25

x + 25  = (y - 5)²

±√(x + 25)  = y - 5

Adding 5 to both sides of the function, we have:

5 ±√(x + 25) = y - 5 + 5

y = f⁻¹(x) = 5 ±√(x + 25)

The airport parking lot charges $2.00 to enter and $3.00 per hour after that. Carmen has N dollars and wants to be able to determine the maximum number of hours she can park. How can Carmen determine the length of time she can afford to park her car in the parking lot?

Answers

Carmen can determine the length of time she can afford to park her car in the airport parking lot by first deducting the entrance fixed charge from her N dollars and then dividing the balance by the hourly rate.

What are the mathematical operations?

The standard mathematical operations that combine numbers, variables, and operands to arrive at a defined output value are addition, subtraction, division, and multiplication.

In this situation, we can use the mathematical operations of subtraction and division to determine the length of time Carmen can park her car.

The fixed charge for entering the airport parking lot = $2

Hourly charger after the initial entrance = $3

The total amount of dollars possessed by Carmen = N dollars.

Let the length of time she can park there = l.

The maximum number of hours she can park is given by the function, F(l) = (N - 2)/3.

Thus, the best strategy for Carmen to determine her parking time at the airport parking lot based on her N dollars, the fixed entrance fee, and the variable cost per hour, is using the mathematical operations of subtraction and division.
