x coordinate of D = distance of 9 - 1 = 8 from point M
y coordinate of D = 4-2 = 2 from point M
so coordinates of D are (--1+8 , -2 + 2) = (7 , 0) answer
Answer:

Step-by-step explanation:
To find the values of
for which, the value of
belongs to
,we solve the inequality;

We multiply through by 8 to obtain;

We subtract 3 to get

Divide through by -1 to obtain;

Or

C2 + a2 +2 = b
Would be the new formula
Answer:
B
Step-by-step explanation:
the supplement is the angle that will add to the other angle to get 180 degrees. 180-129=51 which is B.
