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?

Back

The symbol '≤' means 'less than or equal to'.

Front

What does the symbol '≥' mean?

Back

The symbol '≥' means 'greater than or equal to'.

How do you solve the inequality -4x + 14 ≤ 54?

Back

Subtract 14 from both sides: -4x ≤ 40. Then divide by -4 (remember to flip the inequality): x ≥ -10.

Front

What is the solution to the inequality -9a - 1 < 26?

Back

Add 1 to both sides: -9a < 27. Then divide by -9 (flip the inequality): a > -3.

Front

How do you solve the inequality 11 > -3y + 2?

Back

Subtract 2 from both sides: 9 > -3y. Then divide by -3 (flip the inequality): -3 < y.

Front

What does it mean to graph an inequality?

Back

Graphing an inequality means to represent the solutions of the inequality on a number line, using open or closed circles to indicate whether endpoints are included.

Front

What is the solution to the inequality 5t - 10 > 55?

Back

Add 10 to both sides: 5t > 65. Then divide by 5: t > 13.

Front

Match the graph with the inequality 11 ≤ a.

Back

The graph shows a closed circle at 11 and a line extending to the right.

What is the difference between '>' and '≥'?

Back

'>' means greater than, while '≥' means greater than or equal to.
