Which of the following is the solution to the compound inequality below?
sweet-ann [11.9K]

Answer:

Option D.

x\geq -2  or  x\leq -6

Step-by-step explanation:

<u><em>The correct question in the attached figure</em></u>

we have

3x+5\geq -1 ----> inequality A

subtract 5 both sides

3x\geq -1-5

3x\geq -6

divide by 3 both sides

x\geq -2

The solution of the inequality A is the interval [-2,∞)

-2x-7\geq 5 ----> inequality B

adds 7 both sides

-2x\geq 5+7

-2x\geq 12

divide by -2 both sides

Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

x\leq -6

The solution of the inequality B is the interval (-∞,-6]

therefore

The solution of the system is

x\geq -2  or  x\leq -6
