# How do you evaluate the function f(x) = -2/5x+17 for f(10)?

May 12, 2018

in $f \left(x\right) = - \frac{2}{5} x + 17$,

$f \left(10\right) = 13$

#### Explanation:

$f \left(x\right) = - \frac{2}{5} x + 17$

$f \left(10\right) = - \frac{2}{5} \left(10\right) + 17$

$f \left(10\right) = - \frac{20}{5} + 17$

$f \left(10\right) = - \frac{20}{5} + \frac{85}{5}$

$f \left(10\right) = \frac{65}{5}$

$f \left(10\right) = 13$
