Ответ:
y = 4x/z , y = 4.
Step-by-step explanation:
Recall ; from Variation,
y ∞ x 1
y ∞ ¹/z 2
Now , combine equation 1 & 2 together, it metamorphosed to
y = kx/z 3
Remember, k is a constant and the value must be find first
K = yz/x
= (20 x 3) /15
= 4
To get the equation that models the relationship, we substitute for k in equation 3
y = 4x/z.
To find the value of y , substitute for the values of k, x and z
y = ( 4 x 6 )/6
= ²⁴/₆
= 4
