Based on the graph, all x values are possible so the answer is C.
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
The answer is D.
120 divided by 24 would not give you the price of ONE pen
Answer: y= -2x + 24
Step-by-step explanation
2x - 4y = 24
subtract 2x from both sides
divide 4y by 4y to get y by itself
then you get y= -2x + 24
