The **distance** run by Amy per minute is 0.132 miles.

Given,

The distance run by Amy = 7 miles

**Time taken** by Amy to cover this distance = 53 minutes

We have to find the distance covered by Amy in one minute.

So,

Distance covered by Amy per **minute** = x

Then,

7 / 53 = x / 1

7 × 1 = x × 53

Here,

x = 7/53

Then,

x = 0.132

A x + B y = C represents a **two-variable linear equation** in its standard form. As an illustration, the **conventional form** of the linear equation 2x + 3y = 5 It is rather simple to locate both** intercepts **when an equation is stated in this way (x and y). An** algebraic equation** with simply a constant and a first-order (linear) term, such as y = mx +b, where m is the **slope **and b is the **y-intercept**, is known as a linear equation. The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times. Ax + b = 0, where a and b are two **integers**, and x is a variable, is an example of a linear equation with one variable. This equation has only one **solution.** 2x + 3 = 8, for instance.

tell if the lines are parallel, perpendicular or neither

a- 3x–4y =6 and 3y= –4x+9

A. The **lines **with equation 3x - 4y = 6 and 3y = -4x + 9 are **p****e****r****p****e****n****d****i****c****u****l****a****r**

B. The **lines** with equation y = 1⁄2x - 7 and 6x - 12y = 24 are **p****a****r****a****l****l****e****l**

From the equation of lines, we can detect if they are parallel or perpendicular as follow:

Parallel lines have the same slope (or gradient). Thus, m₁ = m₂Perpendicular lines have slope that have the following property: m₁ × m₂= -1With the above information, we can obatin the answer to the questions. Details below

For question A.

We shall determine the **slope** of each line. This can be obtained as follow:

3x - 4y = 6

Rearrange

4y = 3x - 6

y = 3/4x - 6/4

Comparing y = 3/4x - 6/4 with y = mx + c, the slope is 3/4

3y = -4x + 9

y = -4/3x + 9/3

Comparing y = -4/3x + 9/3 with y = mx + c, the slope is -4/3

Slope (m₁) of 3x - 4y = 6 is 3/4Slope (m₂) of 3y = -4x + 9 is -4/3m₁ × m₂

3/4 × -4/3 = -1

Thus, we can say: 3x - 4y = 6 and 3y = -4x + 9 are **perpendicular**

For question B.

We shall determine the **slope **of each line. This can be obtained as follow:

y = 1/2x - 7

Comparing y = 1/2x - 7 with y = mx + c, the slope is 1/2

6x - 12y = 24

Rearrange

12y = 6x - 24

y = 6/12x - 24/2

y = 1/2x - 12

Comparing y = 1/2x - 12 with y = mx + c, the slope is 1/2

Slope (m₁) of y = 1/2x - 7 is 1/2Slope (m₂) of 6x - 12y = 24 is 1/2m₁ = m₂

Thus, we can say: y = 1/2x - 7 and 6x - 12y = 24 are **parallel **

Rectangle A is 5 in by 7 in. If the scale factor is 4, what is the area of the new rectangle B? How does it compare with the first rectangle?

The area of **rectangle B** is 560 square inches.

**Area of rectangle** is the region occupied by a **rectangle **within its four **sides **or boundaries. The area of a **rectangle **depends on its **sides**. Basically, the formula for area is equal to the product of** length** and **breadth **of the **rectangle**.

Given that,

Given the function below, determine the following.

f(x)= 10x +8

Find f(5).

Find f(-7).

Find a if f(x) = 88.

**Answer:**

Solutions Below.

**Step-by-step explanation:**

These questions test on the concept of **F****u****n****c****t****i****o****n****s**** ****S****u****b****s****t****i****t****u****t****i****o****n****.**

Function Substitution is about giving an input (domain) to a function to produce an output (range)

Example: f(x) = 9x , f(9) = 9(9) = 81

ApplicationWe are given the following function:

f(x) = 10x + 8, where we can express it as

y = 10x + 8

Now we can find the value of f(5) by substituting x = 5 into the function. (Meaning: Find the value of y when x = 5.)

f(5) = y = 10(5) + 8 = 50 + 8 = **5****8**

Next, applying the same concept, we can find the value of f(-7) by substituting x = - 7 into the function. (Meaning: Find the value of y when x = -7.)

f(-7) = y = 10(-7) + 8 = -70 + 8 = **-**** ****6****2**

This last question requires us to work in reverse, where we find the value of x when f(x) = y = 88.

f(x) = y = 10x + 8

10x + 8 = 88

10x = 88 - 8

10x = 80

x = 80 ÷ 10 = **8**

Ahmed recorded a temperature drop of 2 degree F and a second temperature drop of 3 degree F. What is the total change in temperature?

**Answer:**

a drop of 5 degree F, or -5 °F

**Step-by-step explanation:**

You want to know the **total change in temperature** after a **drop of 2 degree F** and a **second temperature drop of 3 degree F**.

The total change will be the sum of changes.

We can figure the total drop in temperature as the sum of drops:

2 °F +3 °F = 5 °F . . . . the total drop in temperature

If we use negative values to represent temperature drops, then the total change can be written as ...

(-2 °F) +(-3 °F) = **-5 °F . . . . . the total change in temperature**

__

*Additional comment*

We often find it convenient to use negative numbers to represent decreases, drops, amounts below some reference level, and so on. Positive numbers can be used for the same purpose if we define the meaning of a positive number in the context.

Here, we can identify a temperature drop by saying it is a drop of 5 degrees, where a positive temperature drop means a change to a lower value. Or, we can say it is a change of -5 degrees, where a positive change is defined as a change to a higher value.

Defining the meaning of positive and negative numbers is especially important when an "improvement" is a reduction in some value (cost, for example). A positive improvement may mean a negative change, and vice versa.

Anupa's favorite fraction is equal to $\frac{5}{3}$. The sum of the numerator and denominator of Anupa's favorite fraction is $160$. What is the difference between the numerator and denominator of Anupa's favorite fraction?

The **difference **between the numerator and denominator of the **fraction **parameters is 40

From the question, the **fraction **is given as

5/3

The above **fraction **can be represented as

5x/3x

This is so because of the following equation

5x/3x = 5/3

The above is calculated by dividing the **numerator **and the denominator by the common factor x

Solving further, we have

Sum of the numerator and denominator = 160

This means that

5x + 3x = 160

Evaluate the sum in the above equation

So, we have

8x = 160

Divide both sides of the fraction by 8

So, we have

x = 20

The required difference is represented as

Difference = 5x - 3x

Evaluate

Difference = 2x

Substitute x = 20 in Difference = 2x

So, we have

Difference = 2 x 20

Evaluate
