8th Math Semester 1 Review

Front

What is the solution to the equation with infinite solutions?

Back

An equation has infinite solutions when it can be simplified to a true statement, such as 0 = 0.

Front

Write an inequality for Craig's parking situation where he wants to spend less than $50.

Back

10 + 5h < 50, where h is the number of hours.

Front

How do you find the x and y intercepts of a linear function?

Back

To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y.

Front

What is the domain of a function?

Back

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

Front

What is the x-intercept of the function 4x - 6y = -48?

Back

The x-intercept is (-12, 0).

Front

What is the y-intercept of the function 4x - 6y = -48?

Back

The y-intercept is (0, 8).

Front

What does the inequality 10 + 5h < 50 represent?

Back

It represents the maximum number of hours Craig can park without exceeding $50.

Front

What is an example of a linear equation?

Back

An example of a linear equation is 2x + 3y = 6.

Front

What does it mean if a function has no solution?

Back

It means there are no values of x that satisfy the equation, often resulting in a contradiction.

Front

What is the significance of the slope in a linear function?

Back

The slope indicates the rate of change of the function; it shows how much y changes for a unit change in x.
