When z kt we say that z varies directly with t. Now lets solve for x x x. So 8 5 1 0 x 8510x 8 5 1 0 x.
The equation of quantities in direct variation is y kx k is the constant of variation The only equation in this form is 4y - 12x that is 4y - 12x divide both sides by 4 y - 3x in form representing direct variation with k - 3 C.
A direct variation is a linear equation that can be written in the form y kx where k is a nonzero constant. This formula is an example of direct variationDirect variation means that in the one term of the formula the variable is on top. Graphically we have a line that passes through the origin with the slope of k. Because we have fraction 52 and 2 in denominator.
