Solve the inequality. Then graph the solution and give interval notation. -21

Sagot :

Interval notation is 1∠ x≤ 2

Explanation

-21≤-6x-9∠ -15

-21≤-6x-9

Grouping the terms, yield

-21+9≤-6x

-12≤-6x

⇒ -6x≥-12

x ≤ 2

Also, -6x-9∠ -15

-6x∠ -15+9

-6x∠ -6

⇒ x is greater 1

Then by combinig the inequalities x is greater than 1 and x ≤ 2, this yields

1∠ x≤ 2
