Step-by-step explanation:
"The diver descends" is a clue that the position of the diver is even lower than before.
Answer:
In Table (b)

Step-by-step explanation:
By definition, Inverse proportion equations have he following form:

Where "k" is the Constant of proportionality.
Solving for "k":
Having the values of "x" and "y" given in each table, you can check if the products of "x" and "y" is equal to a constant value.
Then:
(a) For
:

For
:

For
:

For
:

Since the product of the values of "x" and "y" is not constant, they are not inversely proportional.
(b) For
:

For
:

For
:

For
:

Notice that the Constant of proportionality is:

Therefore "x" and "y" are inversely proportional.
Answer:
2x=y+3
Step-by-step explanation:
make 2x the subject formula
then it becomes equation 1
- 2 3/4 ÷ 5/-9 = - 11/4 x -9/5 = 99/20 = 4 19/20
