I think its f(0) = 3
Thats the only one that sounds true but not sureee
Answer:
12
Step-by-step explanation:
This is a joint variation problem:
z varies directly as x and y
Interpreting this;
z ∝ xy
Therefore;
z = kxy
z = 6, x = 2, y = 6
Now find k,
6 = 2 x 6 x k
6 = 12k
k =
To find the value of z;
x = 3, y = 8
z =
x 3 x 8 = 12
Answer:
{x,y} = {115/17,-23/17}
Step-by-step explanation:
I believe its true.
