The center of an ice rink is located at (0, 0) on a coordinate system measured in meters. Susan is skating along a path that can
Ganezh [65]
We are given:

the center of the rink at the origin.
A skating path (Susan): y = 6x - x^2 - 5
Starting point of Luke = (10, -21) 
Path (Luke) = quadratic eq'n with vertex at (8, -9)
Radius = 35 meters 


The solution that best interprets the path of the skaters is to substitute Luke's starting point to Susan's path or set-up a quadratic equation with vertex of (8,-9) and then equate to Susan's path to solve for their intersection.
