1/2 hour : $1.25 what is the unit rate per hour

$2.50/hour

Step-by-step explanation:

It is given that for hour $1.25.

We have to calculate the unit rate per hour.

Since for   hour the amount = $1.25

for 1 hour the amount would be = 1.25 ÷

                                                    = 1.25 ×

                                                    = $2.50/hour

The unit rate per hour would be $2.50.

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).
