Question

6|5x + 4| − 3 ≤ 93

A) 0 < x < 2 :
B) −9 ≤ x < 9 :
C) x > 2 or x < 0 :
D) −4 < x ≤ 8 :
E) −4 ≤ x ≤ 12/5

Answer 1

Oh, and please explain how you got it.
Or if none of the answers are correct.

Answer 2

I think it may be this --> E) −4 ≤ x ≤ 12/5
but without a solution, that means nothing.
Let me do some work.

Answer 3

6|5x + 4| − 3 ≤ 93
|5x + 4| ≤96/6
By definition of absolute value inequality,
-16 ≤ 5x+4 ≤16
-20 ≤5x ≤12
-20/5≤x≤12/5
-4 ≤ x ≤ 12/5 ---> See what you think about this

Answer 4

Ah...I get it now. Thank you!
