Algebra 1

Compound Inequality - consists of two inequalities connected by “and” or “or”.

Writing Compound Inequalities Ex. 1) Write an inequality that represents the set of numbers and sketch its graph. a.) All real numbers that are greater than or equal to -2 and less than 3. b.) All real numbers that are less than or equal to -3 or greater than 0.

Solving a Compound Inequality with AND Ex. 2) Solve

Solving a Compound Inequality with OR Ex. 3) Solve 6x-5 25.

Reversing Both Inequality Symbols Ex.4) Solve

Compound Inequalities in Real Life Ex. 5) a.) Water is a nonliquid when the temperature is or below, or is at least b.) A refrigerator is designed to work on an electric line carrying from 115 volts to 120 volts.
