Question

Solve the inequality below. Write the solution set using interval notation and graph the solution set on a number line using keyboard symbols as described in class. -4≤-2(x+1)<10

Answer 1

 -4≤-2(x+1)<10

Divide each side by -2.

2≥ x+1>-5

Add -1 to each side.

1≥x>-6

-6<x≤1

Solution interval is (-6,1]

The graph on number line is
