Question

The minimum and maximum temperature for a day in Cupcake Town can be modeled by the equation below:

3|x − 8| + 15 = 18

What are the minimum and maximum temperatures for this day?

Answer 1

3 |x - 8| + 15 = 18
3 |x - 8| = 3
|x - 8| = 1

x - 8 = 1 -(x - 8) = 1
x = 1 + 8 -x + 8 = 1
x = 9 -x = 1 - 8
-x = -7
x = 7

minimum = 7, maximum = 9
