What does it mean if an inequality is written with a 'greater than or equal to' symbol (≥)?

Back

It means that the variable can take on values that are greater than or equal to a certain number.

What is the difference between 'greater than' (>) and 'greater than or equal to' (≥)?

Back

'Greater than' (>) means the value cannot equal the number, while 'greater than or equal to' (≥) includes the number itself as a possible solution.

How do you check your solution for an inequality?

Back

To check your solution, substitute the value back into the original inequality to see if it makes the inequality true.
