What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or not equal to the other. Examples include: x < 5, y ≥ 3.

How do you solve the equation m - 13 = 33?

Back

To solve for m, add 13 to both sides of the equation: m = 33 + 13, so m = 46.

What is the solution to the equation 2t = 20?

Back

To solve for t, divide both sides by 2: t = 20 / 2, so t = 10.

What does an open circle on a number line represent?

Back

An open circle on a number line indicates that the endpoint is not included in the solution set. For example, x < 4 is represented with an open circle at 4.

What does a closed circle on a number line represent?

Back

A closed circle on a number line indicates that the endpoint is included in the solution set. For example, x ≤ 4 is represented with a closed circle at 4.

What is the first step in solving the inequality x < 4?

Back

The first step is to identify the boundary point, which is 4, and then determine the values that are less than 4.

How do you graph the inequality x ≥ -4?

Back

To graph x ≥ -4, place a closed circle at -4 and shade to the right to indicate all values greater than or equal to -4.
