If Y Varies Directly As X at Collection Of Questions And Answers

If Y Varies Directly As X. Substitute y=18 and x=5 in equation (1). What is the direct variation equation if y varies directly with x, and #y=2# when #x=4#?

If y varies inversely as the square of x, and y = 40 when x = 2, find y
If y varies inversely as the square of x, and y = 40 when x = 2, find y from sciemce.com

That means y y varies directly with x x. If y varies directly as x, find the constant of variation k and the direct variation equation for the situation. Divide each value of y y by the corresponding value of x x.

If y varies inversely as the square of x, and y = 40 when x = 2, find y

Y = 10 when x = 2. The value of y when x = 5 is y = 3 x 5 = 1 5. (1) where, k is constant of proportionality. This means that the equation is of the form y = k x where k is any number.
