The coordinates of the endpoints of the diameter of a circle are (-1,5) and (3, -1). The center of the circle has coordinates

ans=(-2,2)

Step-by-step explanation:

let the end point of circle diameter (-1,5) and (3,-1) be (x1,y1) and (x2,y2) respectively

using mid point formula

(x,y)=(-1,5)/2+(-3,-1)/2  [center point is equal to mid point of  diameter)

       =  (-1+(-3))/2+(5-1)/2

       =(-2,2)

center coordinate of circle=(-2,2)

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

thats not a system of equations, that is a solution
