7R Intro to 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?

Back

The symbol < means 'less than'. For example, 3 < 5 means 3 is less than 5.

Front

What does the symbol > mean?

Back

The symbol > means 'greater than'. For example, 7 > 4 means 7 is greater than 4.

Front

What does the symbol ≤ mean?

Back

The symbol ≤ means 'less than or equal to'. For example, 5 ≤ 5 means 5 is less than or equal to 5.

Front

What does the symbol ≥ mean?

Back

The symbol ≥ means 'greater than or equal to'. For example, 6 ≥ 4 means 6 is greater than or equal to 4.

Front

How do you compare negative integers?

Back

When comparing negative integers, the one with the larger absolute value is actually smaller. For example, -5 < -2.

Front

What is the result of comparing 10 and 20?

Back

10 < 20, meaning 10 is less than 20.

Front

What is the result of comparing -24 and -11?

Back

-24 < -11, meaning -24 is less than -11.

Front

If x > 8, which value makes the inequality false?

Back

The value 5 makes the inequality x > 8 false.

Front

What is the opposite of the inequality x < 5?

Back

The opposite is x ≥ 5.
