Let f (x) = - 5x - 4 and g (x) = 6x - 7. Find f (x) + g (x)

A. x - 11

B. - 11x = 3b

C. - 11x - 11

D. x + 3

Simple ...

if f (x) = - 5x-4 and g (x) = 6x-7

And you want f (x) + g (x)

then just add ... f (x) + g (x)

-5x-4+6x-7

1x-11

This is the answer to f (x) + g (x) = 1x-11

Thus, your answer.
