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

x = 1, x = 17
x = −7, x = 9
x = 7 x = 9
No solution
( i think its no solution )

Answer 2

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

this means that

x-8 = 1 x = 9

and x - 8 = -1

x = 7

minimum temperature = 7 and maximum temperature = 9
