-5x + 1 ≥ 11 or 4x + 3 ≥ -13

Question

Solve the compound inequality. Except for the empty set, express the solution set in both set-builder and interval notations. Graph the solution set on a number line.

Answer 1

x < or = -2 from 1st inequality

x > or = -5/2 from 2nd inequality

x is in the interval [-2.5, -2]

{x|-5/2 </= x </= -2}
