Answer:

D: (x,y) -> (2x, 2y)

Step-by-step explanation:

Take a look at the top of the roof, in the small house it is at (6,4) and in the big house it is at (12, 8).

To get from (6,4) to (12,8) you have to multiply x and y by 2.

You can test this with multiple points. Only the  (x,y) -> (2x, 2y) mapping works for all of them.

Assoli18 [71]
<h3>Answer:  53%</h3>

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

Explanation:

The question asks "What percent of females participate in extracurricular activities?" This means we only focus on the second column. There are 36 women, and of this total, 19 are in extracurricular activities.

Dividing the two values leads to approximately 19/36 = 0.52777 which rounds to 0.53

Then we move the decimal to the right two spots to get 53%

Roughly 53% of the female students participate in extracurricular activities.

Determine the value of a 10 year old car that costs $24,500 new and depreciates by 9% every year
son4ous [18]
First, we need to know how much the car depreciates each year. Multiply the price of the car by the percentage.

We can turn 9% into a decimal by moving the decimal point two places to the right.

9% = .09

24500 * .09 = 2205

Multiply the product by the amount of years you want to predict the price at.

2205 * 10 = 22050

Subtract that from the original price of the car.

24500 - 22050 = 2450

The value of a 10 year old car that costs $24500 and depreciates 9% every year will cost $2450.

Solve the equation the square root of the quantity x plus 4 minus 3 equals 1 for the variable.
Kruka [31]

Answer:

x = 12

Step-by-step explanation:

sqrt(x+4) - 3 = 1

First get the sqrt all by itself on one side of the equation. Add 3 to both sides of the equation.

sqrt(x+4) = 1 + 3

sqrt(x+4) = 4

To "fix" the sqrt, that is, "undo it" and get rid of it, you have to SQUARE both sides of the equation.

(sqrt(x+4))^2 = 4^2

x + 4 = 16

subtract 4 to finish up.

x = 12

Check:

sqrt(12 + 4) - 3 = 1

sqrt16 - 3 = 1

4 - 3 = 1

1 = 1 Check!
