If y varies jointly as x and z and y = 12 when x = -2 and z=3, find y when x is 4 and z is -1
jeka57 [31]

Answer:

D. 8​

Step-by-step explanation:

y varies jointly as x and z

y = k(xz)

-------------------------

Find k, the constant of variation

y = 12 when x = -2 and z=3

12 = k(-2 * 3)

12 = k(-6)

k = -2

-------------------------

find y when x is 4 and z is -1

using k = -2

y = -2(4 * -1)

y = -2(-4)

y = 8
