f(x) = -3x +9
g(x) = 8x +7
Find f(x) +g (x)
can you show me how to solve this?
Thank you for your help.

hi
write them together
8x-3x(x terms or variables) + 9+7(constants)
solve x terms sepsrately and constants separately and add
5x +16
Done
Hope this helps you.

Just add the two expressions together:
f(x) + g(x) = -3x+9+8x+7 = 5x+16.

f(x) + g(x) = (-3x + 9) + (8x + 7)
= -3x + 9 + 8x + 7
= 5x + 16

f(x) +g (x)
=-3x+9+8x+7
=5x+16

(-3x+9) + (8x+7)
= 5x+16

f(x)+g(x)=-3x+9+8x+7=(-3+8)x+(9+7)=5x+16

perhaps you mean f(g(x)) , then,
it's u = -3(8x+7) + 9
if you mean g(f(x) , then ,
its v = 8(-3x+9) + 7
