D/7.29 = 1.5/4.05
d = (1.5/4.05)7.29 = 2.7
In both cases, we have cooling. We can add together the 2 functions describing this cooling: z(x) = 0.5x - 9 - [-x-2] = 0.5x - 9 + x + 2, or
z(x) = 1.5x - 7
Provided that this is correct, all we have to do now is to subst. 5 for x:
z(5) = 1.5(5) - 7 = 7.5 - 7 = 0.5 (answer)
