What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols such as <, >, ≤, or ≥.

Front

What does the symbol '>' mean in an inequality?

Back

The symbol '>' means 'greater than'. For example, x > 5 means x is any number greater than 5.

Front

What does the symbol '<' mean in an inequality?

Back

The symbol '<' means 'less than'. For example, x < 3 means x is any number less than 3.

Front

What does the symbol '≥' mean in an inequality?

Back

The symbol '≥' means 'greater than or equal to'. For example, x ≥ 4 means x is any number greater than or equal to 4.

Front

What does the symbol '≤' mean in an inequality?

Back

The symbol '≤' means 'less than or equal to'. For example, x ≤ 2 means x is any number less than or equal to 2.

Front

How do you solve the inequality x + 9 > 21?

Back

Subtract 9 from both sides: x > 12.

Front

What is the solution to the inequality z ≤ 9?

Back

The solution includes all numbers less than or equal to 9.

Front

What are two solutions to the inequality x < 8?

Back

Examples of solutions include 7 and 0.

Front

How do you graph the solution of the inequality -11w > -11?

Back

Divide both sides by -11 (remember to flip the inequality): w < 1. Graph all numbers less than 1.

Front

What does it mean to match a graph with its inequality?

Back

It means to identify the correct inequality that represents the shaded region of the graph.
