Which does not show a direct variation between x and y?
a. y = x/9 b. y = 2xc. y = 0.5x d. y = 9/x
if f(x) varies directly with x, and f(x) = 8 when x = 6, write the direct linear variation equation.
a. f(x) = 3/4x b. f(x) = 6x c. f(x) = 8x d. f(x) = 4/3x
find the constant of variation for the relationship f(x)= 30x. a.10 b.30 c. x d. f(x)
if f(x) varies directly with x, and f(x) = 56 when x = 8, find the value of f(x) when x = 2 a.4 b.7 c.8 d.14
