The minimum for g(x)=x2-10
36
Any number thats 8.5 or above
-10x+8 and 5x-4 is a possible combination. Those are both linear equations when added together will give you -5x+4
Answer:
They have no minimum y -value
4x^2 + 5xy - y^2 = 6
Implicitly differentiating both sides,
4(2x) + 5(x y' + y) - 2yy' = 0
where y' = dy/dx
8x + 5xy' +5y -2yy' = 0
combining y' terms
y' (5x-2y) +8x +5y = 0
y'(5x-2y) = -(8x+5y)
dy/dx = -(8x+5y)/(5x-2y)
or
dy/dx = (8x+5y)/(2y-5x)
