Question 506646: How to solve a compound inequality and graph the solutions?
EX: -6 < 2x - 4 < 12
Answer by jennywecas(28) (Show Source): You can put this solution on YOUR website!
-6 < 2x - 4 < 12
add 4 to all 3 parts
-2 < 2x <16
divide 2 from all 3 parts
-1 < x < 8
to graph you put an open circle on the point (-1,0) and then you put an open circle on the point (8,0).Then draw a line between the 2
