What is a flat rate in a pricing model?

Back

A flat rate is a fixed charge for a service, regardless of the amount used or consumed.

Front

How do you calculate the total cost when there is a flat rate and a variable charge?

Back

Total Cost = Flat Rate + (Variable Charge per unit * Number of units used).

If Jayden has 30 pounds of garbage and is charged $13, what is the variable charge per pound?

Back

Let x be the variable charge per pound. The equation is 13 = flat rate + 30x. Solve for x.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you determine if a point is a solution to a system of equations?

Back

Substitute the x and y values of the point into both equations. If both equations are true, the point is a solution.

Front

What does it mean for a line to be 'greater than' or 'less than' in an inequality?

Back

'Greater than' means the area above the line, while 'less than' means the area below the line.

Front

What is a system of inequalities?

Back

A system of inequalities consists of two or more inequalities that share the same variables.

Front

How do you graph a system of inequalities?

Back

Graph each inequality on the same coordinate plane and identify the overlapping region that satisfies all inequalities.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x = 0.

Front

How do you solve for y in a linear equation?

Back

Rearrange the equation to isolate y on one side, typically in the form y = mx + b.
