One and Two Step Inequalities

Front

What is an inequality?

Back

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

Front

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

Back

The symbol '<' means 'less than'. For example, n < 6 means n is less than 6.

Front

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

Back

The symbol '>' means 'greater than'. For example, n > 6 means n is greater than 6.

Front

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

Back

The symbol '≤' means 'less than or equal to'. For example, n ≤ 6 means n is less than or equal to 6.

Front

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

Back

The symbol '≥' means 'greater than or equal to'. For example, n ≥ 6 means n is greater than or equal to 6.

Front

How do you solve the inequality n < 6?

Back

To solve n < 6, you identify all values of n that are less than 6.

What is the solution to the inequality -7 + 10z > -27?

Back

The solution is z > -2.

Front

When graphing the inequality n < 6, what type of dot is used?

Back

An open dot is used when graphing n < 6.
