Determine `A` and `B` so that` y = = A/x+ Bx` has a minimum at the point `(1,6).`

If f(x) = a/x +bx has minimum at (2,1) then (a,b) =

If xy(y-x)=16 then y has a minimum value when x=

If xy(y-x)=16 then y has a minimum value when x=

If f(x)=bx^(2) + ax has minimum at (2, -12) then (a , b)-=..

The curve y=ax^2+bx has minimum at (2,-12) on it. Then (a,b) =

Determine the positions of the points (1, -1) with respect to the circle x^(2) + y^(2) - 4x + 6y + 4 = 0 .

If y = (ax + b)/((x-1)(x-4)) has a maximum value at the point (2, -1) then find the values of a and b.

Determine the values of x and y so that the line joining the points A(x,3,1),B(1,1,-2) is parallel to the line joining the points C(2,5,3),D(-4,y,-6).

Determine the values of x and y so that the line joining the points A(x,3,11),B(1,1,-2) is parallel to the line joining the points C(2,5,3),D(-4,y,-6).
