You and your friend skate at the same rate. You complete 5 laps in 7 minutes. How long does your friend take to complete 15 laps?

21 minutes

Step-by-step explanation:

You have to calculate how long it takes you to go around once so divide 7/5 to get 1.4 then multiply that by your friends laps to get 21 minutes.

hope this helped!!

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
