Use the given information to find f '(8).
f(x) = 9g(x) + h(x)
g(8) = 1 and g'(8) = 5
h(8) = 8 and h'(8) = -3

f'(8)=

well, clearly, since

f = 9g+h
f' = 9g'+h', so
f'(8) = 9g'(8)+h'(8) = 9*5-3 = 42

Of course -- that's the answer to the Ultimate Question of Life, the Universe, and Everything!

I suspect a typo, since g(8) and h(8) are not used, but maybe there are other related problems not posted.
