Using the following equation, find the center and radius:

x2 + 2x + y2 + 4y = 20
The center is located at (1, 2), and the radius is 25.
The center is located at (−1, 2), and the radius is 25.
The center is located at (−1, −2), and the radius is 5.
The center is located at (1, 2), and the radius is 5.

  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.

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
