3. is it possible to solve x (t ) for t, substitute it into y(t) to eliminate the parameter, t, and write it as a rectangular equation with x and y instead? why or why not? these are the equations i am working with: •x (t)=0.0411905(t^2)+(-0.164619)t+28.0114 and • y (t)=-0.024127(t^2)+(-0.591143)t+(-87.4403)
