Y varies directly as x and y =18 when x=1/2 write an equation that relates y and x
marusya05 [52]

Answer:

y = 36x

Step-by-step explanation:

Given that y varies directly as x, then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 18 when x = \frac{1}{2}, thus

k = \frac{y}{x} = \frac{18}{\frac{1}{2} } = 36

y = 36x ← equation of variation
