What is the equation for calculating total charges when a plumber charges a flat fee plus an hourly rate?

Back

Total Charge = Flat Fee + (Hourly Rate * Hours Worked)

Front

If a plumber charges a $50 flat fee and $30 per hour, how would you express the total charge for 'h' hours of labor?

Back

Total Charge = 50 + 30h

Front

How do you solve the equation 2x + 5 = 15 for x?

Back

Subtract 5 from both sides: 2x = 10, then divide by 2: x = 5.

Front

What is the solution to the equation 3x - 7 = 14?

Back

Add 7 to both sides: 3x = 21, then divide by 3: x = 7.

Front

How do you determine if a point lies on the graph of a linear equation?

Back

Substitute the x-value of the point into the equation and see if the resulting y-value matches the y-value of the point.

Front

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

Back

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

Front

What does the slope of a line represent in a real-world context?

Back

The slope represents the rate of change between two variables.

Front

If a school buys books for $12 each and spends $480, how do you find the number of books purchased?

Number of books = Total spent / Cost per book = 480 / 12 = 40.

Front

What is the first step in solving the equation 2x + 5 = 15?
