Answer:
392
Step-by-step explanation:
m = 8 and n = 14
Substituting the values of m and n in the question, we get :
7m + 3mn
=( 7 x 8) +(3 x 8 x 14)
= 56 + 336
= 392
D. x=3
I don't really know how to explain it other than the only points on the line are sitting at the x=3 and y=anything
F(x)=-4(-1)-5
f(x)=4-5
f(x)= -1
-1 is your answer
