Writing and Graphing Inequalities Practice

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols such as <, >, ≤, or ≥.

Front

What does the symbol '>' mean in an inequality?

Back

The symbol '>' means 'greater than'. For example, x > 5 means x is greater than 5.

Front

What does the symbol '<' mean in an inequality?

Back

The symbol '<' means 'less than'. For example, x < 3 means x is less than 3.

Front

What does the symbol '≥' mean in an inequality?

Back

The symbol '≥' means 'greater than or equal to'. For example, x ≥ 4 means x is greater than or equal to 4.

Front

What does the symbol '≤' mean in an inequality?

Back

The symbol '≤' means 'less than or equal to'. For example, x ≤ 2 means x is less than or equal to 2.

Front

How do you represent 'more than twenty students' in inequality form?

Back

s > 20, where s represents the number of students.

Front

How do you represent 'at most forty-five dollars' in inequality form?

Back

g ≤ 45, where g represents the amount of money.

Front

What inequality does the number line graph with an open circle at -4 represent?

Back

x < -4, indicating that -4 is not included in the solution set.

Front

If x ≤ 4, what values can x take?

Back

x can take any value less than or equal to 4.

Front

Which of the following is NOT a solution for x < -4? -6, -5.3, -4, -4.1

Back

-4 is NOT a solution because it is not less than -4.
