If `(5x^2-3y^2):xy=11:2` then `x/y=`

If (5x^(2)-3y^(2)):xy=11:2 then what is the positive value of (x)/(y) ?

Write True or False If (5x-2y):(2x+3y) = 2:3 then x:y = 12:11

If (4x^2-3y^2):(2x^2+5y^2)=12:19 then x:y=

If (5x^(2)-3y^(2))/(xy)= (11)/(2) , find the positive value of (x)/(y)

If (5x+7y):(3x+11y)=2:3 , then find x:y.

If A=(x^3+y^3)/((x-y)^2+3xy), B=((x+y)^2-3xy)/(x^3-y^3), C=(xy)/(x^2-y^2) then (A-:B)xxC=

If 2x^(2)+5xy+2y^(2)-11x-7y+K=0 is the pair of asymptotes of the hyperbola 2x^(2)+5xy+2y^(2)-11x-7y-4=0 then K=

If 2x^(2)+5xy+2y^(2)-11x-7y+K=0 is the pair of asymptotes of the hyperbola 2x^(2)+5xy+2y^(2)-11x-7y-4=0 then K=

Subtract 2x^2-3xy from the sum of x^2-3y^2+11xy and y^2-4x^2+9xy

If x ^(2) + 5xy + y^(2) =-2x + y -6=0 then y'' at (1,1) is
