What does the symbol '<' mean?

Back

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

Front

What does the symbol '>' mean?

Back

The symbol '>' means 'greater than'. For example, x > 3 means x is greater than 3.

Front

What does the symbol '≤' mean?

Back

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

Front

What does the symbol '≥' mean?

Back

The symbol '≥' means 'greater than or equal to'. For example, x ≥ 20 means x is greater than or equal to 20.

Front

How do you represent 'no more than 20' in inequality form?

Back

You represent 'no more than 20' as x ≤ 20.

Front

How do you represent 'more than -2' in inequality form?

Back

You represent 'more than -2' as x > -2.

Front

What is the graph of the inequality k < 3?

Back

The graph of k < 3 is a number line with an open circle at 3 and shading to the left.

Front

What is the graph of the inequality x ≤ 20?

Back

The graph of x ≤ 20 is a number line with a closed circle at 20 and shading to the left.

Front

What is the graph of the inequality x > 3?

Back

The graph of x > 3 is a number line with an open circle at 3 and shading to the right.
