Question 292239: Here's a question from my homework I dont know how to solve, It says: Suppose that "Y" varies jointly with "W" and "X" and inversely with "2" and "y=36", when "w=3", "x=18" and "z=6". Write the equation that models the relationship. Then find when w=3, x=2, and z=4.
Thankyou!

Suppose that "Y" varies jointly with "W" and "X" and inversely with "z" and "y=36", when "w=3", "x=18" and "z=6". Write the equation that models the relationship. Then find when w=3, x=2, and z=4.
:
y =
:
"y=36", when "w=3", "x=18" and "z=6".
Find k
= 36
:
= 36
:
9k = 36
k =
k = 4
then
y = ; is the equation
;
Then find when w=3, x=2, and z=4.
y =
y =
y =
y = 6
