Question

Solve and graph the absolute value inequality: |2x + 1| ≤ 5.

Answer 1

First pull out a 2 to make the coefficient of x 1

Answer 2

so you have |x+1/2| less than or equal to 5/2

Answer 3

draw a number line and mark a point 1/2....do 1/2 +5/2 which is 3 and mark that to the right of 1/2

Answer 4

do 1/2-5/2 which is -2 and mark that point to the left of 1/2

Answer 5

since we have less than or equal to in the question we have to put closed circles at -2 and 3 and connect them with a solid line...u then have your graph
