Back

An inequality is a mathematical statement that compares two expressions using inequality symbols such as <, >, ≤, or ≥.

Front

What does the symbol '≤' mean?

Back

The symbol '≤' means 'less than or equal to'.

Front

What does the symbol '≥' mean?

Back

You represent 'at least' using the '≥' symbol.

Front

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

Back

You represent 'no more than' using the '≤' symbol.

Front

What is the graph of the inequality b ≤ -2?

Back

The graph includes all numbers less than or equal to -2, represented with a closed dot at -2 and a line extending to the left.

Front

When do you use an open dot on a graph?

Back

You use an open dot when the inequality is strict, meaning it uses < or >.

Front

When do you use a closed dot on a graph?

Back

You use a closed dot when the inequality includes ≤ or ≥.

Front

Write the inequality for: 'x is greater than 50'.

Back

x > 50.

Front

Write the inequality for: 'a is less than or equal to 11'.
