The graph for the first is line segment joining (x, y) = (−2,−4)and (2, 4), sans the end points. The second part is the line through (-2, -6) and (-3, -9), from (-2, -6), excepting (-2, -6). ..
Step-by-step explanation: you are using y for the piecewise function.
5(n-10)=40 is the equation
5n-50=40 solve for n
5n = 90
n =18

Answer:
Elena's running speed is 5 miles/hour
Explanation:
The speed is defined as the covered distance per unit time
In the problem, we have:
The distance covered is the length (circumference) of the circular track which is given as of a mile.
We are also given that she completes each lap (she completes of a mile) in of an hour
To get her speed, we will divide the distance covered by the time taken to cover this distance
This is done as follows:
speed = miles/hour
This means that:
Elena can run 5 miles each hour
Hope this helps :)
