The answer is -25. tried tested and approved. welcome
9x+1 is the answer.
I hope this helped
Step-by-step explanation:
5x + 2y = 10
Ax + By = C
A = 5
B = 2
C = 10
4 people in 60 minutes =
1 person in 15 minutes
3 people = 45 minutes
An ellipse (oval shape) is expressed by the following equation:

where h is the x coordinate of the center and k is the y coordinate of the center. Furthermore, a is the horizontal distance from the center, and b is the vertical distance from the center. Lastly, c is the distance from the center to one of the foci (they are spaced apart equally).
We can find the foci by using

36 - 11 =


Since the k value in this case is 0, the y value of both foci are 0. Also, since h and k are both 0, we know the center of the ellipse is at the origin.
So the foci are (-5, 0) and (5, 0)
Hope this helps :)
