What does the symbol '>' mean in inequalities?

Back

The symbol '>' means 'greater than'. For example, x > 5 means x is any number greater than 5.

Front

What does the symbol '<' mean in inequalities?

Back

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

Front

What does the symbol '≥' mean in inequalities?

Back

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

How do you represent the inequality 11 ≥ a on a number line?

Back

You draw a solid dot on 11 and shade to the left, indicating all numbers less than or equal to 11.

Front

Is -4 a solution for the inequality p ≥ -3?

Back

No, -4 is not a solution because -4 is less than -3.

Front

Is 0 a solution for the inequality p < -4?

Back

No, 0 is not a solution because 0 is greater than -4.
