Question

*** Will give you a medal ***
Suppose that y varies jointly with w and x and inversely with z and y = 360 when w = 8, x = 25, and z = 5. Write the equation that models the relationship. Then find y when w = 4, x = 4, and z = 3.

Answer 1

@hartnn

Answer 2

y varies jointly with w and x --> \(y=kwx\)
y varies inversely with z--->\(y=k'/z\)
so, overall,
\(y=kwx/z\)

Answer 3

got that^ ?

Answer 4

ya now plug it in

Answer 5

yes, you will be able to find k then....

Answer 6

k=9

Answer 7

yes, correct :)

Answer 8

what about y when w = 4, x = 4, and z = 3.

Answer 9

so it is 48 ?
