On a bicycle, Rosa rides for 3 hours and is 20 miles from her house. After riding for 5 hours, she is 32 miles away. What is Rosa's rate?

Rosa's rate is 6 miles per hour

Step-by-step explanation:

Rosa rides for 3 hours and is 20 miles from her house.

After riding for 5 hours, she is 32 miles away

Let x represents the number of hours

and y represents the number of miles away

(3,20)  and (5,32)

rate is the slope

to find rate we find change in miles over change in hours

so Rosa's rate is 6 miles per hour

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
