Question

Only for sutff to do

Answer 1

If the output of the function is 5, then the input is

1. 8. ( optionC)

2. 9 ( Option D)

3. 0( option A)

4. The equation for the situation is y = x -5 ( option D).

It expresses a unique output for each input, exemplified by f(x) in algebraic terms.

In the equation;

y = x -3

the output is y

therefore;

5 = x -3

x = 5+3 = 8

Therefore the input value is 8.

2. The input value will be

x = y × 2

x = 4.5 ×2 = 9

3. The input value will be

x = 6 - 6

= 0

4. let y be the cost after the coupon and x is before the coupon

y = x - 5

Answer 2

Hey, so sorry for answer so late! I wasn't on here for a while, and I didn't get your message until I logged back in.

1.) C. 8, because if you add 3 and 5, you get 8, which is your answer.

2.) D. 9, because 9/2 equals 4.5

3.) A. 0, because if you start off with zero and add 6, you will get 6.

4.) D. y = x - 5, because when you subtract 5 from 42.50, you get 37.50, which is our desired result.

Hope this helps ya, and again, sorry about the inconvenience of answering so late. Feel free to ask more questions by messaging me on this question. Have a good day :D
