Question

Solve the compound inequality and graph the solutions.1

Answer 1

A compound inequality is formed by two inequalities, with diferent values ≤≥<>

Then first divide the inequality in

1≤ x + 7

and

x + 7< 5

then first becomes

-x ≤ 7-1≤6 or same x≥ -6

second inequality becomes

x < 5-7 < -2

then the composed inequality solution is

-6 ≤ x < -2
