Graph and Solve One Step Inequalities

Front

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, n > 7 means n is greater than 7.

Front

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

Back

The symbol '<' means 'less than'. For example, n < 5 means n is less than 5.

Front

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

Back

The symbol '≥' means 'greater than or equal to'. For example, h ≥ -9 means h is greater than or equal to -9.

Front

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

Back

The symbol '≤' means 'less than or equal to'. For example, x ≤ 4 means x is less than or equal to 4.

Front

How do you solve the inequality 7n > 49?

Back

Divide both sides by 7: n > 7.

Front

How do you solve the inequality 24 ≤ h + 15?

Back

Subtract 15 from both sides: h ≥ 9.

Front

How do you solve the inequality z ≤ 9?

Back

The solution is z ≤ 9, meaning z can be any number less than or equal to 9.

Front

What does a closed dot on a number line represent?

Back

A closed dot represents that the number is included in the solution set, used for ≤ or ≥.

Front

What does an open dot on a number line represent?

Back

An open dot represents that the number is not included in the solution set, used for < or >.
