What is an inequality?

Back

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

Front

How do you solve the inequality -2k > 18?

Back

Divide both sides by -2, remembering to flip the inequality sign: k < -9.

Front

What does the expression 8v - 4(v + 8) = 8 simplify to?

Back

It simplifies to v = 10.

Front

What is the result of the expression 17 + (8/2) - 10(2)?

Back

The result is 1.

Front

How do you interpret the graph of an inequality?

Back

The graph shows the set of all possible solutions that satisfy the inequality.

Front

What is the equivalent expression for -4 - (-2)?

Back

The equivalent expression is -4 + 2.

Front

What does it mean if k is less than -9 in the inequality -2k > 18?

Back

It means that k can take any value that is smaller than -9.

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows that one expression is greater or less than another.

Front

How do you graph the inequality k < -9?

Back

You draw a number line, place an open circle at -9, and shade to the left.

Front

What is the solution set for the inequality -2k > 18?

Back
