Answer:
(-4,1)
Step-by-step explanation:
Point A is located at (−2, −6), and D is located at (−6, 8).
We need to find the midpoint of A and D
Mid point formula is 
Point A is (-2,-6) that is (x1,y1)
Point D is (-6,8) that is (x2, y2)
plug in the values in the formula



Mid point is (-4, 1)
Answer:
3(x + 4) = 3(x) + 3(4)
3(x + 4) = 3x + 12
3x + 12 = 3x + 12
Subtract 12 from both sides
3x + 12 - 12 = 3x + 12 - 12
3x = 3x
3x - 3x = 3x - 3x
= 0
Yes because the median and range are not a function of the totality of the sample set, the median is just value that is halfway of the set and the range is the difference of the highest and lowest value. As long as the lowest and highest value and the halfway value are the same in each set, the median and range will be equal no matter what the other values of the set are.
