Answer: 270

Explanation:

Given:
f(x)=7+4x and
g(x)=(1)/(2x)

Then, the rational function (f/g) is given by :-

$(f/g)(x)=(f(x))/(g(x))\\\\\Rightarrow\ (f/g)(x)=(7+4x)/((1)/(2x))\\\\={2x(7+4x)}$

Now, the value of (f/g) is given by :-

(f/g)(5)=2(5)(7+4(5))=270

Hence, the value of (f/g) (5) = 270.
