Answer:
-8
Step-by-step explanation:
Given that x and y are two variables. they are related by the function
y =8-2x
Since x and y are related, given one value we can find the other using this equation.
In our question, given that x =8
Substitute x value in the equation
y = 8-2x
y =8-2(8) = -8
Hence answer is -8:
Verify: We verify by putting -8 for y and check whether x =8
-8=8-2x
Or 2x = 16
x =8

Answer:
- domain: x < -2
- range: y > 1
Step-by-step explanation:
Domain and range of the inverse function are swapped: the domain of the function is the range of its inverse, and vice versa.

B) the additive inverse of -3 is +3, so 17-(-3) = 20 is your answer.
Remember, two negatives = one positive, and so:
- (-3) = 3
17 + 3 = 20
Therefore, B is your answer
hope this helps
