Question

PLEASE HELP!!!

Solve |2x – 9| + 4 < 7. You must show all work. Use >= and <= to represent the inequalities. Use complete sentences to describe the graph in words.

Answer 1

|2x-9|+4<7
subtract 4 from both sides
|2x-9|<3
now
|a|<b implies -b<a<b
so you have
-3<2x-9<3
add 9 to all terms
6<2x<12
divide by 2 on all terms
3<x<4

Answer 2

sorry fixed typo

Answer 3

THANKS BRO!! LIFE SAVER.

Answer 4

should be 3<x<6...sorry its late

Answer 5

Answer 8

yeah after lookin through it understood it thanks again bro!
