Solving Linear Inequalities

Front

What is a linear inequality?

Back

A linear inequality is a mathematical statement that compares a linear expression to a value using inequality symbols such as <, >, ≤, or ≥.

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

Back

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

Front

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

Back

The symbol '<' means 'less than'. It indicates that the value on the left side of the inequality is smaller than the value on the right side.

Front

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

Back

The symbol '≥' means 'greater than or equal to'. It indicates that the value on the left side is either larger than or equal to the value on the right side.

Front

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

Back

The symbol '≤' means 'less than or equal to'. It indicates that the value on the left side is either smaller than or equal to the value on the right side.

How do you solve the inequality X + 6 > 10?

Back

Subtract 6 from both sides: X > 4.

Front

How do you solve the inequality 5z - 2 - 2z < 13?

Back

Combine like terms: 3z - 2 < 13, then add 2 to both sides: 3z < 15, and finally divide by 3: z < 5.

How do you solve the inequality -7x + 15 ≥ -20?

Back

Subtract 15 from both sides: -7x ≥ -35, then divide by -7 (remember to flip the inequality): x ≤ 5.

Front

What is the solution to the inequality 77 ≤ 5 + 8n?

Back

Subtract 5 from both sides: 72 ≤ 8n, then divide by 8: 9 ≤ n or n ≥ 9.

What does an open circle on a number line represent?

Back

An open circle represents that the number is not included in the solution set, typically used for < or > inequalities.
