Answer:
Suppose the closest point is at p=(x0,y0), and set q=(−2,−3). Then the tangent to the parabola at p is perpendicular to ℓ, the line through p,q. and we end up numerically computing the roots from here.
Answer:
a triangle witih side lengths of 12,16,20
Y≤x/3-1 AND y≤x/3-3
So for BOTH inequalities to be true:
y≤x/3-3
The sides in parentheses times 2 for each is equal to the perimeter expression.
Maybe 11x? i dont really know, thats all the info we get
