Answer:
Step-by-step explanation:
We can do 'point' arithmetic.
M = (A+B)/2
2M = A+B
B = 2M - A
We have M(3, -4) and A(8, -5)
B = 2(3, -4) - (8, -5) = (6,-8) - (8,-5) = (-2, -3)
Check:
(A+B)/2 = ( (8+-2)/2, (-5+ -3)/2) = (3, -4) good
Answer: (-2, -3)
We must first open the parenthesis. We get 15*7+15y, or 105+15y. We can now add 12 to 105 which would be 117. Now we have -4-5y+117+15y. With this we can move the -4 to 117 which is 113 and the -5y to 15y which is 10y. So we got 113+10y as our answer.
