| 3x-6 | <9 Graph the solution set

OpenStudy (anonymous):

i still dont understand

OpenStudy (anonymous):

It's asking what values of x make | 3x - 6 | less than 9. You can graph this by drawing y = | 3x - 6 | on a Cartesian coordinate plane and then looking at which values of x make the y value less than 9.

|dw:1322430762423:dw|

OpenStudy (anonymous):

but shouldnt i make an equation for -9 as well?

OpenStudy (anonymous):

meaning 3x-6 > -9?

OpenStudy (anonymous):

| 3x-6 | <9 means -9<3x-6<9

OpenStudy (anonymous):

the numbers that would work are ONLY between -1 and 5? or could the be greater that 5 and less than -1?

OpenStudy (anonymous):

only between -1 and 5

OpenStudy (anonymous):

thank you

| 3x-6 | <9 --> -9 < 3x-6 < 9 --> a. -9 < 3x-6 and b. 3x-6 < 9 --> a. -9-(-6) < 3x -->-3 < 3x -->-1 < x (A) --> b. 3x-6 <9 -->3x < 9-(-6) -->3x < 15 --> x< 5 (B) (A) and (B) mean -1 < x < 5
