Im not sure what the question is asking but my guess would be c)18.
Should we simplify or solve for m...?
Answer:
-30
Step-by-step explanation:
f(x) = 3 so f(-8) = 3;
g(x) = 5x + 7, so g(-8) = 5(-8) + 7 = -33
Then (f + g)(-8) = 3 - 33 = -30
This is the sum of two functions both evaluated at x = -8.
30in I know that because I just did this .this is EASY!
