What is the solution set of an inequality?

Back

The solution set of an inequality is the set of all values that satisfy the inequality.

What is a compound inequality?

Back

A compound inequality consists of two or more inequalities joined by 'and' or 'or'.

Front

How do you solve a compound inequality?

Back

To solve a compound inequality, solve each inequality separately and then combine the solutions.

Front

What is the transitive property of inequalities?

Back

The transitive property states that if a < b and b < c, then a < c.

Front

What is the addition property of inequalities?

Back

The addition property states that if you add the same number to both sides of an inequality, the inequality remains true.
