<span>Given that f(x) = 2x + 5 and g(x) = x − 7
</span>f(g(x)) = 2(x − 7) + 5
f(g(x)) = 2x - 14 + 5
f(g(x)) = 2x - 9
when x = −3 , f(g(-3)) = 2(-3) - 9 = - 6 - 9 = -15
Answer
<span>A. −15</span>
The first one is 40:5 becasue when you divide 40 by 8, you get 5.
The second one would probably be 42:8.4 becuase when you divide 42 by 5, you get 8.4
I'm not so sure about the secod one but i am positive about the first one.
Hope this helps!! :D
