Presentation transcript:

Multiplying each side of an inequality by a ______________ number produces an _________________________. Multiplying each side of an inequality by a ______________ number and ___________________________________. positive Equivalent inequality negative reverses the direction of the inequality Just remember, when you multiply or divide by a negative number, _____________________. flip the inequality

Reminder: you must flip the inequality reduce

You don’t have to flip the inequality because you are dividing by a positive number 01

Have to flip the inequality because we multiplied by a negative number

The quotient of x and 18 is greater than or equal to

The product of -8 and c is less than
