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:

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

$1km=1000m=10^3m\\\\1m=100cm=10^2cm\\\\1km=10^3\times10^2cm=10^5cm\Rightarrow1cm=10^{-5}km\\\\5.82\times10^4cm=5.82\times10^4\times10^{-5}km=5.82\times10^{4-5}km=5.82\times10^{-1}km\\\\\boxed{5.82\times10^4cm=5.82\times10^{-1}km=0.582km}$

ehidna [41]

Answer:

In explanation

Step-by-step explanation:

First, we simplify the parentheses:

$(12x+16)-7x=(10x-20)+6$

Simplify:

$5x+16=10x-14$

Isolate x:

$30=5x$

Divide 5 by both sides

$x=6$
