Question

A heated piece of metal cools according to the function c(x) = (.5)x − 11, where x is measured in hours. A device is added that aids in cooling according to the function h(x) = −x − 3. What will be the temperature of the metal after 5 hours?

Answer 1

what i did is plugged the second h(x)= -x-3 in for x in the first equation and then solved

Answer 2

so
.5(-x-3)-11=5
