i'll give medal Which does not show a direct variation between x and y? A. y = 5x B. y = 6/x C. y = 0.7x D. y = x/9

When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation.

OpenStudy (anonymous):

@Radelp no direct answers

OpenStudy (anonymous):

im being nice and tellling it. To be more "mathematical" about it, if y varies directly as x, then the graph of all points that describe this relationship is a line going through the origin (0, 0) whose slope is called the constant of the variation.

OpenStudy (anonymous):

no your not you said A!!!

OpenStudy (anonymous):

can you help with this question If f(x) varies directly with x, and f(x) = 10 when x = 4, write the direct linear variation equation. A. f(x) = 10x B. f(x) = 4x C. f(x) = 5/2x D. f(x) = 2/5x

OpenStudy (anonymous):

i know, its the answer

OpenStudy (anonymous):

can you answer this question please If f(x) varies directly with x, and f(x) = 10 when x = 4, write the direct linear variation equation. A. f(x) = 10x B. f(x) = 4x C. f(x) = 5/2x D. f(x) = 2/5x

OpenStudy (anonymous):

C

Thank you
