Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or not equal to the other.

Front

What does the graph of y < -2x + 1 represent?

Back

It represents all the points (x, y) that satisfy the inequality, meaning y is less than -2 times x plus 1.

Front

How do you find the slope of a line from its equation?

Back

The slope can be found in the slope-intercept form (y = mx + b), where m is the slope.

Front

What is the slope of a line perpendicular to a line with a slope of 2?

Back

The slope of a line perpendicular to a line with slope 2 is -1/2.

Front

What is the y-intercept of the line represented by the equation y = 2x + 3?

Back

The y-intercept is the point where the line crosses the y-axis, which is (0, 3) in this case.

Front

How do you solve the equation 6(4x + 5) = 3(x + 8) + 3?

Back

Distribute, combine like terms, and isolate x to find the solution.

Front

What does the variable x represent in the equation 5x + 2y = 48?

Back

In this context, x represents the cost of each adult ticket.

Front

How do you determine the flat rental fee from the cost of renting a van?

Back

Set up a system of equations based on the given costs and miles driven to solve for the flat fee.

Front

What is the formula for calculating the cost of renting a van?

Back

Cost = Flat fee + (Cost per mile * Number of miles driven).

Front

What is the solution to the equation 3x + 2y = 32 when y = 8?

Back

Substituting y = 8 gives 3x + 16 = 32, so x = 16/3.
