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 'greater than'. For example, x > 5 means x is 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 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 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 less than or equal to 2.

Front

How do you represent 'the product of 6 and a number n is at least 24' as an inequality?

Back

Front

When solving an inequality, when do you flip the inequality sign?

Back

You flip the inequality sign when you multiply or divide both sides by a negative number.

Front

What is the solution to the inequality x > 5?

Back

The solution includes all numbers greater than 5.

Front

How can you graph the inequality x < 3?

Back

You would draw a number line, place an open circle at 3, and shade to the left to indicate all numbers less than 3.

Front

What does the solution to the inequality x ≤ 4 look like on a number line?

Back

You would draw a number line, place a closed circle at 4, and shade to the left to indicate all numbers less than or equal to 4.
