Suppose that y varies directly with x and interversely with z, and y=18 when x=15. Write the equation that models the relationship Then find y when x=21 and z=7

Nnesha (nnesha):

interversely ?? ;o

Nnesha (nnesha):

inversely right ?

OpenStudy (anonymous):

Yeah, whatever that means. Lol

Nnesha (nnesha):

okay @lol

OpenStudy (anonymous):

Im so exhausted from looking at questions i dont understand

Nnesha (nnesha):

okay equation for direct variation is y = kx and inverse variation is y = k/x <--- inverse so k is dividing by x

OpenStudy (anonymous):

okay

Nnesha (nnesha):

|dw:1431318887384:dw| inverse k/z so that's how you should write an equation for this question
