Step-by-step explanation:
2(3x+4)=56
<=> 6x+8=56
<=> 6x=48
<=> x=8
Answer:
The constant of variation k is 3/2.
The value of z is -30.
Step-by-step explanation:
As we know Function form is
Z=kxy-------------1
So for k
K = z/xy
So if z=18, x=2 y=6
k= 18/2 x6
k= 18/12
k=3/2
Now we have to find for z, now we know the value of x= -4 y =5 z =3/2
z= kxy
z= 3/2 (-4)(5)
z= -30
