Back

The symbol '<' means 'less than'. For example, x < -8 means x is less than -8.

Front

What does an open dot on a number line represent?

Back

An open dot indicates that the number is not included in the solution set. For example, x > 4 is represented with an open dot on 4.

Front

What does a closed dot on a number line represent?

Back

A closed dot indicates that the number is included in the solution set. For example, x ≥ 4 is represented with a closed dot on 4.

Front

How do you graph the inequality x > 4?

Back

You place an open dot on 4 and shade the area to the right.

Front

How do you graph the inequality x < -8?

Back

You place an open dot on -8 and shade the area to the left.

What is the inequality for 'eight less than a number is less than 10'?

Back

The inequality is n - 8 < 10.

Front

What is the inequality for 'four more than a number is more than 13'?

Back

The inequality is n + 4 > 13.

Front

What is the inequality for 'fourteen more than a number is greater than 9'?

Back

The inequality is n + 14 > 9.
