Question 1018615: Part 1. Rewrite the inequality as an equivalent pair of inequalities without absolute values or as a 3-part inequality.
|4x+5| -7>/=8
***>/= means greater than or equal to. not =8
Part2. Solve the inequality.
Part 3. Express answer in interval notation, and in set builder notation. Express where shaded area is on number line.

|4x+5| -7>=8
abs(4x-5)>=15
4x-5>=15; 4x>=10,x>=2.5
if x=3, abs (17)-7>=8 true.
------------------------------
4x+5<=-15
4x<=-20
x<=-5
check with -6
abs(-19)-7>=8
12>=8, true
----------------
