Front

What does the inequality 6 > x mean?

Back

x is any number less than 6.

Front

Solve for x: 2x - 3 + 4x = 27

Back

x = 5.

Front

What is the range of a graph if it is defined as 1 ≤ y ≤ 5?

Back

The range includes all y-values from 1 to 5, inclusive.

Front

What is a Positive Interval in a graph?

Back

A Positive Interval is where the graph is above the x-axis.

Front

Is the point (3, 1) a solution for the inequality y < 2x + 1?

Back

No, because it is located on the line and the line is dotted.

Front

What is the solution to the inequality x + 4 < 10?

Back

x < 6.

Front

Define the term 'domain' in relation to functions.

Back

The domain is the set of all possible input values (x-values) for a function.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as x increases, y also increases.

Front

What is the slope of a line represented by the equation y = 3x + 2?

Back

The slope is 3.

Front

How do you find the x-intercept of the equation 2x + 3y = 6?

Back

Set y = 0 and solve for x: x = 3.
