Nina has 25 tennis balls and hal has 30.

which equation can be used to calculate how many more tennis balls hal has than nina?

a.
x + 25 = 30

b.
x – 30 = 25

c.
25 – x = 30

d.
30 + 25 = x

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
