How do you represent the inequality for values of v shown on a number line?

Back

The inequality for v can be represented as v > a or v < b, depending on the endpoints shown on the number line.

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows that one expression is greater than or less than another.

What does the symbol > mean?

Back

The symbol > means 'greater than'. It indicates that the value on the left is larger than the value on the right.
