Rebecca and Jessica have each come up with a study plan. - Rebecca studies for 60 minutes one night. Each night after that, she studies for half the time she did the night before. - Jessica studies for 55 minutes one night. Each night after that, she studies for 5 fewer minutes than she did the night before. Determine whether each study plan has a linear or nonlinear relationship.

Rebecca's plan is nonlinear, Jessica's plan is linear

Rebecca's plan is linear, Jessica's plan is nonlinear

A figure with 2 parallel sides is shown. Select all the statements that are true about the image of the figure after a reflection across the horizontal axis.

The side lengths of the image have the same length as those of the preimage.

Two of the sides of the image are parallel.

The side lengths of the image are twice as long as those of the preimage.

The side lengths of the image are half as long as those of the preimage.

The angles of the image have half the measure as those of the preimage.

What type of association exists between a car’s age and its resale price?

Strong positive linear association

Weak positive linear association

Which line best models the relationship between the variables.

None; the relationship is not linear.

Select all the statements that are true about the ordered pair (−2, 3) and the system of equations y = $$-\frac{1}{2}x + 2$$ and y = $$-3x - 1$$ .

(−2, 3) lies on the graph of y = $$-\frac{1}{2}x + 2$$ , so it is a solution to the first equation.

(−2, 3) does not lie on the graph of y = -3x - 1, so it is not a solution to the second equation.

(−2, 3) is a solution to only 1 of the equations, so it is not a solution to the system.

(−2, 3) lies on the graph of y = -3x - 1, so it is a solution to the second equation.

Because (−2, 3) is a solution to both equations, it is a solution to the system.
