7) One track coach wants his athletes to race 5 miles around a track to measure how fast
Lady bird [3.3K]
Five laps? I don’t know if you meant to put that the track is a mile around, but if the track is a half mile around, an athlete would have to run 10 laps around the track to run 5 miles.
X=5/y, so x would be how many laps the athletes run, and y would be the length of the track. Hope this helps

Please help me out with this !!!!!!!
laila [671]

Answer:

y = 2x - 1

Step-by-step explanation:

Consider the differences between consecutive values of y. If constant then this value is the multiplier.

1 - (- 1) = 3 - 1 = 5 - 3 = 7 - 5 = 9 - 7 = 2 ← constant difference, hence

y = 2x

Given the point (0, - 1 ) then we require to subtract - 1, that is

y = 2x - 1 ← equation relating x and y
