Write an appropriate direct variation equation if y = 27 when x = 9
Write an appropriate inverse variation equation if y = 2 when x = 9
If y varies directly as x, and y = 15 as x = 3, find y for the xvalue of 4.
If y varies inversely as x, and y = 5 as x = 6, find y for the xvalue of 10.

Best ResponseYou've already chosen the best response.0yup, hence the required equation is y = 3x. Dat sit.

Best ResponseYou've already chosen the best response.0same!! because yk = x , then y = (1/k)x , that is one of the form y = nx where n = 1/k.

Best ResponseYou've already chosen the best response.0Oh yeah the curved graph with two lines is the inverse. And those equations are 1/x... so in our case.?
