Answer:
Table C
Step-by-step explanation:
For x and y to be proportional , then the values of
= constant k
Table B
= = 2
= = 4
The values are not constant
=
= =
These values are constant
Then Table C shows a proportional relationship between x and y
h^2=x^2+y^2, here x and y are equal so we can say
h^2=2x^2, we see that h=2(2^(1/2)) so
2x^2=8
x^2=4
x=2
split the other three in half
