<em><u>Write the equation that represents this relationship</u></em>
The constant is -3
<em><u>Solution:</u></em>
Given that,
y varies jointly as x and z, and inversely as w
Therefore,
Where, k is constant of propotionality
y = 3 when x = -2, z = 6, and w = 12
Substitute in eqn 1
Write the equation that represents this relationship
Substitute k = -3 in eqn 1
Thus the equation is found
