Answer:

z = kxy

6= k(3)(8)

6 = 24k

k= 1/4

z= 1/4xy

z= 1/4(6)(4)

z=24/4

z = 6 A.

Step-by-step explanation:

Answer:

A. 6

EQUATION:

z = kxy

FIND THE CONSTANT OF VARIATION:

k = $\frac{z}{xy}$

k = $\frac{6}{(3)(8)}$

k = $\frac{6}{24}$

k = $\frac{1}{4}$

FIND z WHEN x = 6 and y = 4:

z = kxy

z = ( $\frac{1}{4}$ )(6)(4)

z = $\frac{12}{2}$

z = 6
