Question

If f(x) = 7 + 4x and g(x)= 7x, what is the value of (f/g)(5)

Answer 1

27/35

Explanation:

(f/g)(5) means f(5)/g(5).

So we will need to find both f(5) and g(5).

f(5) means replace x with 5 in f. This gives us 7+4×5.

Let's simplify 7+4×5:

7+4×5

7+20

27.

g(5) means replace x with 5 in g. This gives us 7×5.

Simplifying 7×5 gives us 35.

(f/g)(5)=f(5)/g(5)=27/35.
