If y varies directly as x, and y = 15 as x = 3, find y for the xvalue of 4.
The answer is 2
If y varies inversely as x, and y = 5 as x = 6, find y for the xvalue of 10.
k = 60?

Best ResponseYou've already chosen the best response.0Nope. y =15, x =3, hence k =5, your equation is y = 5x, then if x =4, y = 20, not 2

Best ResponseYou've already chosen the best response.0if y is varies inversely as x, that is y = k/x , k/x = 5 when x =6, hence k = 30 , not 60 y = 30/x, if x =10 , y = 3 hey!! I worked!!! not you. why???

Best ResponseYou've already chosen the best response.0\(y =kx\\15 = k*(3)\\k = \dfrac{15}{3}=5\)

Best ResponseYou've already chosen the best response.0Now, find y if x =4, just replace x =4 into it \(y = (5)*4= 20\)
