Front

What does the inequality k < 3 represent on a number line?

Back

It represents all values of k that are less than 3, which is shown as an open circle at 3 and a line extending to the left.

Front

What is the value of 2(3^4)?

Back

162

Front

How do you solve the inequality r - 14 ≥ 17?

Back

Add 14 to both sides to get r ≥ 31.

Front

What inequality represents the cooling of the ice rink temperature?

Back

71 - 3.5x < 50.

Front

What is the solution to the equation -5x = 25?

Back

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is less than, greater than, less than or equal to, or greater than or equal to the other.

Front

What does the expression 3^4 mean?

Back

It means 3 multiplied by itself 4 times, which equals 81.

Front

How do you graph the inequality k < 3?

Back

Draw a number line, place an open circle at 3, and shade to the left.

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

What does the term 'solution' mean in the context of inequalities?

Back

A solution to an inequality is any value that makes the inequality true.
