Step-by-step explanation:
It’s c bc the square root of 9 is 3, while square root of 2 is not a clean answer
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
Answer:
Step-by-step explanation:
s= student ticket
g= general admisson ticket
4s+6g=2876
s+g=525
4s+6g=2876
-4s-4g=-2100
add both equations
2g=776
g=388
s+g=525
s+388=525
s=137
