Answer:
B = (6, 4)
Step-by-step explanation:
You know that the midpoint is calculated as ...
M = (A +B)/2
Solving this for B, we find ...
2M = A + B
B = 2M - A
Filling in the coordinate values, we get ...
B = 2(5, -2) -(4, -8) = (2·5-4, 2(-2)+8)
B = (6, 4)
Answer:
Sustitute the y-values into the equation.
For y=10,
2(10) + 3 (10 - 5)
20 + 3(5)
20+15
35
For y=57,
2(57) + 3 (57 - 5)
114 + 156
270
For y=35
2(35) + 3 (35 - 5)
70 + 3(30)
70 + 90
160

Answer:
Donation received in December = $ 25,400
Step-by-step explanation:
Given:
Average for 11 months = $20,600
Average for entire year = $ 21,000
Total amount received in first 11 months (A) = $20,600 x 11
= $226,600
Total amount received in entire year( 12 months) (B) = $ 21,000 x 12
= $252,000
Therefore,
Amount received in December month = (B) - (A)
= $252,000 - $226,600
= $ 25,400
