Find the constant of variation for the relation and use it to write an equation for the statement. then solve the equation.

k = ⅔

d. y = ⅔xz; y(6, 3) = 12

Step-by-step explanation:

        y ∝ x and y ∝ z, so

        y ∝ xz and

(1)      y = kxz               Divide each side by xz

        k = y/(xz)            Let x = 1, z =4, y = ⁸/₃

           = (⁸/₃)/(1 × 4)

           = ⁸/₃ × ¼          Cancel 4s

(2)   k = ⅔                Substitute into (1)

        y = ⅔xz              Let x = 6, z = 3

        y = ⅔ × 6 × 3     Cancel 3s

       y = 2 × 6

       y = 12

y(6, 3) = 12

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
