Step-by-step explanation:

7) 2x+3=-2x+15

y=2(3)+3

y=6+3

y=9

8)x= -1(1+2y)/3

-4-2y=-6

y=1

x=-2(1+2(1))/3

x=-2

6)2x-16=-12

Please finish the functions on these 7,8 please 10 points :)
puteri [66]

What you have so far is correct.

Problem 7 is a function because none of the x values repeat. Each x input goes to exactly one y output. The y values can repeat. If the y values repeat, then we don't have a one-to-one function.

In contrast, problem 8 is not a function. We have x = 1 go to y = 8 and y = 6 at the same time. This is one example showing we don't have one output for a given input.
