1) Y=x-3, if the output value is “5”, then we can rewrite it as 5=x-3. Then add 3 to both sides, so x=8.

2). If the function says to add 6 to the input, and the output is 6, then the input must be 0.

Or put another way, 6=x+6, x can only be 0.

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
