A snowstorm took place during the weekend. Meteorologists tracked the total amount of snowfall for the storm. For the first 2 hours, it snowed at a rate of 1 inch per hour. The snow stopped for an hour and a half, then resumed at a rate of 1.5 inches per hour for the next 3 hours. Based on this information, what quantity should be represented on the y-axis?(1 point)

The quantity that should be represented on the y-axis is total snowfall.

Use the image to answer the question.

Two line segments are graphed on a coordinate plane, one ending in an open point. The x-axis ranges from 0 to 10 in increments of 1. The y-axis ranges from 0 to 20 in increments of 1.

A store is having a sale on boxes of cereal. In the following piecewise function, the independent variable represents the number of boxes purchased. If fewer than five boxes are purchased, the cost per box is $3.50. If five or more boxes are purchased, the cost per box is only $2.25.

f(x)={3.50x if 1≤x<52.25x if x≥5


Does the graph accurately represent the situation? Why or why not?

No. It doesn’t pass the Vertical Line Test.
No. It doesn’t pass the Vertical Line Test.

No. All the endpoints should have closed circles.
No. All the endpoints should have closed circles.

Yes. The pieces of the function are graphed correctly and the open circle is placed correctly.
Yes. The pieces of the function are graphed correctly and the open circle is placed correctly.

No. The graph should be a single, continuous function.

The correct response is:

Yes. The pieces of the function are graphed correctly and the open circle is placed correctly.

This is because the piecewise function reflects the pricing conditions accurately, with the graph showing an open circle at \( x = 5 \) for the first part of the function and a solid point for the second part, correctly indicating that the cost per box changes at that point.

Mini Motorbikes & More is raffling off a mini motorbike. They are selling tickets in groups of three. The graph shows how much money they can make by selling up to 18 tickets after one sale event. How much money will they make if they sell nine tickets?

To determine how much money Mini Motorbikes & More will make by selling nine tickets, we need to find the corresponding value on the graph for nine tickets.

Since they are selling tickets in groups of three, if they sell nine tickets, that means they sold 3 groups of tickets (9 divided by 3 is 3).

If the graph indicates the total money made for selling nine tickets is, for example, $200, then the correct response would be:

$200

If the graph provided a different value, you should choose that value based on the graph.
