We start eliminating the same numbers with the same variable. So we take out 5y on both equation. We then subract 3x to 6x and we do the same to the right side. We end up having 3x=12 and then we divide 12/3=4. We plug 4 on the x values in one of the equation to find out the y value on that equation. You end up with y=3 and then plug that in the same equation on both to see if its right. Finally after that its correct.

A cheater travels at a rate of 90 ft./s the distance d traveled by the cheetah is a function of seconds traveled t right rule fo

HACTEHA [7]

So the equation for this would be y= 90x where y would be the distance in feet covered in x seconds and x would be seconds. So to find out the distance covered in 25 seconds you would plug in 25 for x.

y= 90(25)
y= 2250

So to answer the question you would say that the cheetah would cover 2,250 feet in 25 seconds.
