Using the average rate of change, it is found that the average rate is of:
(1) 2.1 °F per minute
<h3>What is the average rate of change of a function?</h3>
It is given by the <u>change in the output divided by the change in the input</u>.
In this problem:
- At 15 minutes, the temperature was of 90ºF.
- At 45 minutes, the temperature was fo 153ºF.
Hence, in 30 minutes, the temperature increased 63ºF, hence the rate is given by:
r = 63/30 = 2.1 °F per minute.

Answer:
x = -2
Step-by-step explanation:
Solution:
-5x - 5y = 25 -(1)
3x + 5y = -21 -(2)
Adding (1) and (2),
-5x - 5y + 3x + 5y = 25 - 21
-5x + 3x -5y + 5y = 4
-2x = 4
x = 4 / -2
Therefore, x = -2
