What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using inequality symbols (such as <, >, ≤, ≥) to show that one expression is larger or smaller than the other.

How do you solve the inequality -8(3+5x) > -184?

Back

First, distribute -8: -24 - 40x > -184. Then, add 24 to both sides: -40x > -160. Finally, divide by -40 (remember to flip the inequality): x < 4.

What is the solution to the inequality 14 < -2x + 6 - 2x?

Back

First, simplify: 14 < -4x + 6. Then, subtract 6 from both sides: 8 < -4x. Finally, divide by -4 (flip the inequality): x < -2.

What does the graph of x > 2 look like?

Back

The graph of x > 2 is a number line with an open circle at 2 and a line extending to the right, indicating all values greater than 2.

What is the difference between 'and' and 'or' in inequalities?

Back

'And' means both conditions must be true simultaneously, while 'or' means at least one of the conditions must be true.
