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

devlian [24]

Answer:

f(25/29) = $\frac{20}{29}$

Step-by-step explanation:

In order to do this problem, we need to plug in $\frac{25}{29}$ for x. When we plug it in we get $f(x) = -5(\frac{25}{29}) + 5$ . After this we can start by multiplying. When we multiply $-5(\frac{25}{29} )$ we get $(\frac{-125}{29}) + 5$ . 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 $(\frac{-125}{29}) + \frac{145}{29}$ because when changing the denominator we have to multiply the numerator by the same number. After adding these fractions we get our answer of $\frac{20}{29}$ .
