Given the function f(x) = -5x + 1 + 3, for what values of x is f(x) = -12?

irina1246 [14]

Answer:

$x=\frac{16}{5}$

Step-by-step explanation:

The given function is

$f(x) = -5x +1+3$

Which can be rewritten also as

$f(x) = -5x +4$

We want to find the values of x for which

$f(x) = -12$

In order to do that, we just substitute -12 into f(x), and we solve the equation for x:

$-12 = -5x + 4\\-16 = -5x\\x=\frac{-16}{-5}=\frac{16}{5}$
