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

'>' means 'greater than'. For example, x > 5 means x is greater than 5.

Front

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

Back

'<'' means 'less than'. For example, x < 3 means x is less than 3.

Front

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

Back

'≥' means 'greater than or equal to'. For example, x ≥ 10 means x is greater than or equal to 10.

Front

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

Back

'≤' means 'less than or equal to'. For example, x ≤ 20 means x is less than or equal to 20.

Front

How do you represent 'more than 100' in an inequality?

Back

x > 100.

Front

How do you represent 'at least 54 inches' in an inequality?

Back

x ≥ 54.

Front

How do you represent 'no more than 250 pounds' in an inequality?

Back

x ≤ 250.

Front

What type of circle is used when graphing an inequality like x < 6?

Back

An open circle is used to indicate that 6 is not included in the solution.

Front

What type of circle is used when graphing an inequality like x ≤ 4?

Back

A closed circle is used to indicate that 4 is included in the solution.
