What is the full text of the exercise? What were the instructions? What is the meaning of the "set" (?) within the curly braces?4X^2+9Y^2 = 12XY
{(X varies as 1/Y) , (X varies as y) , (X varies as 2/3 Y) , (X = 2/3Y)}
I think the answer to the equation is x/y = 3/2
but I'm not sure what type of variation is it
4X^2+9Y^2 = 12XY
{(X varies as 1/Y) , (X varies as y) , (X varies as 2/3 Y) , (X = 2/3Y)}
I think the answer to the equation is x/y = 3/2
but I'm not sure what type of variation is it
4X^2+9Y^2 = 12XY
4X^2+9Y^2 - 12XY = 0
(2*X - 3*Y)^2 = 0
2*X - 3*Y = 0 ..................... so you are correct that the equation actually is X/Y = 3/2
Y = 2/3 * X ........................... What kind of variation is this?
That is what I chose... but my teacher counted my answer as wrongDirect variation...
