Question

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
whats that awnser ? a,b,c,d?

Answer 1

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

Answer 2

awnser this one too >>>>>Solve for x: −3|2x + 6| = −12

x = 1 and x = 5

x = −1 and x = −5

x = −9 and x = 3

No solution
a,b,c,d?

Whenever you see ANYTHING like this.

|x| solutions can be +x or -x
