{71.NS.6b and 18.NS.6c} The three points (4,0), (-6,0), and (-6,-4) form three corners of a rectangle. Determine the coordinates of the fourth point.

(4,-4)

Step-by-step explanation:

Diagonals of a rectangle share a common midpoint

(4-6)/2 , (0-4)/2 = (-6+x)/2, (0+y)/2

-2 = -6 + x

x = 4

-4 = y

step-by-step explanation:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
