Unit 2 EOU Review

Front

What does the inequality x ≥ 48 represent in the context of height requirements for a roller coaster?

Back

It means that a person must be at least 48 inches tall to ride the roller coaster.

Front

Which point is a solution to the inequalities represented in a graph?

Back

A solution is a point that satisfies all inequalities in the system, such as (1, 0) being a solution.

Front

Solve the inequality: 2x < -3x + 15

Back

x < 3

Front

Solve the inequality: -2(x + 2) < 14

Back

x > -9

Front

Is the point (3, 1) a solution for a dotted line inequality?

Back

No, because it is located on the line and the line is dotted, meaning it is not included.

Front

What does a dotted line in a graph of an inequality indicate?

Back

A dotted line indicates that points on the line are not included in the solution set.

Front

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

Back

It means 'greater than' and indicates that the value on the left is larger than the value on the right.

Front

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

Back

It means 'less than' and indicates that the value on the left is smaller than the value on the right.

Front

What is the solution set of the inequality x ≤ 48?

Back

The solution set includes all values of x that are less than or equal to 48.

Front

How do you graph the inequality x > 3?

Back

You draw a number line, place an open circle at 3, and shade to the right.
