Back

True

Front

Which graph represents the inequality x ≥ 23?

Back

Graph A: Number line with an open circle at 23 and arrow to the right.

Front

Front

Write an inequality to show how many sweaters Melissa can buy if she spends no more than $300 on school clothes, having spent $75 on a coat and each sweater costs $10.

Back

75 + 10x ≤ 300

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is greater than, less than, or not equal to the other.

Front

What does it mean for a relation to be a function?

Back

A relation is a function if each input (x-value) has exactly one output (y-value).

Front

What is the solution set of the inequality x < 5?

Back

All real numbers less than 5.

Front

How do you graph the inequality x > 2?

Back

Draw a number line, place an open circle at 2, and shade to the right.

Front

What is the difference between a closed circle and an open circle on a number line?

Back

A closed circle indicates that the number is included (≤ or ≥), while an open circle indicates that the number is not included (< or >).
