Question

If f(x)=3-2x and g(x)=1/x+15, what is the value of (f/g)(8)?

Answer 1

Answer:
`((f)/(g))(8)=-(104)/(121)`

Explanation:

`f(x)=3-2x\\g(x)=(1)/(x)+15`

`((f)/(g))(8)=(3-2x)/((1)/(x)+15 ) \\((f)/(g))(8)=(3-2(8))/((1)/(8)+15 )\\((f)/(g))(8)=(3-16)/((1+120)/(8) ) \\((f)/(g))(8)=(-13)/((121)/(8) )\\((f)/(g))(8)=(-13)((8)/(121) )\\((f)/(g))(8)=-(104)/(121)`
