Math1: Module 3 Inequalities/Open/Closed

Front

What does the inequality x > 5 mean?

Back

The values of x must be greater than 5.

Front

Which number is not a solution to the inequality x > 5?

Back

5 is not a solution because it is not greater than 5.

Front

What type of circle is used on a number line for the inequality A ≥ B?

Back

A closed circle is used because the value is included.

Front

What does the symbol A < B represent?

Back

A is less than B.

Front

What type of circle is used on a number line for the inequality A < B?

Back

An open circle is used because the value is not included.

Front

How is the interval notation for x ≤ -2 represented?

Back

The interval notation is (-∞, -2].

Front

What does the symbol A ≤ B indicate?

Back

A is less than or equal to B.

Front

What is the difference between open and closed intervals?

Back

Open intervals do not include endpoints, while closed intervals do.

Front

How would you express the solution set for x > 3 in interval notation?

Back

The interval notation is (3, ∞).

Front

What does the inequality x < 4 mean?

Back

The values of x must be less than 4.
