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

3 times Ix-8I +15=18, yes?

Answer 2

3|x − 8| + 15 = 18
3|x − 8| = 3

Answer 3

3 times Ix-8I, yes?

Answer 4

But how does that get me to the answer ? I'm confused

Answer 5

C

Answer 6

\(\bf 3|x - 8| + 15 = 18\implies 3|x - 8| =18-15\implies 3|x - 8| =3\\ \quad \\
|x - 8|=1\implies
\begin{cases}
+(x - 8)=1\\ \quad \\
\bf -(x - 8)=1
\end{cases}\)

Answer 7

9 ?

Answer 8

3(1)+15=18
right?

Answer 9
