When multiplying or dividing an inequality by a negative, you MUST change the sign of the inequality. Which of the following would you have to change the inequality sign for? (Check all that apply)

• x+3 > -7

• -3x < 9

• -5x > 10

Answer explanation

Ex: -3x > 9, you have to divide by -3. To do that, it would become

x < -3 because you must change the sign of the inequality when you divide by a negative.

If you are just adding or subtracting you don't change the sign.

You don't change the sign if you are multiplying/dividing by a positive number.
