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?

x = 1, x = 17
x = −7, x = 9
x = 7 x = 9
No solution

Answer 1

x = 7 x = 9

Explanation:

Answer 2

First subtract 15 from both sides, you get 3/x-8/ = 3
Now divide both sides by 3, you get /x-8/ = 1
Now set x - 8 = 1 and x - 8 = -1 So, x = 9 and x = 7
Seems like the minimum is 7 and maximum is 9.
