Can some one please help me solve these: 1) y = -3/2x + 12
2) y = 3/2x + 12
3) y = -3/2x - 12
4) y = 3/2x - 12
5) y = 4/5x + 4
6) y = -4/5x + 4
7) y = 4/5x -4
8) y = -4/5x - 4
9) y = 12
10) y = -12
11) x = -10
12) x = 10

Aheated piece of metal cools according to the function c(x) = (.5)x ? 7, where x is measured in hours. a device is added that aids in cooling according to the function h(x) = ? x ? 2. what will be the temperature of the metal after two hours?
