Get x all by itself and everything else on the opposite side of x.

-12 = 8 - 4x
-20 = -4x <-- Subtract 8 from each side
5 = x <-- Divide both sides by -4

So, x is equal to 5.

In Exercise, solve the equation for k. <br> 22 = 32e-0.02k
lesya692 [45]

Answer:

18.6

Step-by-step explanation:

We are given that

22=32e^{-0.02k}

We have to find the value of k.

Divide by 32 on both sides then we get

\frac{22}{32}=e^{-0.02k}

\frac{11}{16}=e^{-0.02k}

Taking ln on both sides then we get

ln\frac{11}{16}=-0.02k

lne=1

ln11-ln16=-0.02k

log\frac{m}{n}=logm-logn

2.398-2.77=-0.02k

-0.372=-0.02k

k=\frac{-0.372}{-0.02}=18.6

Hence, the value of k=18.6
