Question

Find f (25/29) if f (x)=-5x+5

Answer 1

f(25/29) =
`(20)/(29)`

Explanation:

In order to do this problem, we need to plug in
`(25)/(29)` for x. When we plug it in we get
`f(x) = -5((25)/(29)) + 5`. After this we can start by multiplying. When we multiply
`-5((25)/(29) )` we get
`((-125)/(29)) + 5`. Since the fraction cannot be simplified any further, we can now add 5. In order to add 5 we need to find a common denominator, which in this case will be 29. Changing the denominator to 29 gives us
`((-125)/(29)) + (145)/(29)` because when changing the denominator we have to multiply the numerator by the same number. After adding these fractions we get our answer of
`(20)/(29)`.
