Step-by-step explanation:

Since 2x+y>4 you get y>4-2x. Then you draw the line y=4-2x then you are interested in everything above the line not including it since it is y>4-2x so it is a dashed line. You need to shade the side that satifies the inequality and since it is every pair (x,y) where y>4-2x, you need to shade everything above the line which is the side that does not include the origin. So the answer is C.
The midpoint, M, of points A and N is (8,10) because;
Point A is (-6,-6) which has a slope of 8/7 (rise/run) with M, (1,2). So, if 8/7 is repeated/ added to M, it will be point N.
1+7=8 (run/x)
2+8=10 (rise/y)
Put x and y together to get (8,10).
N= (8,10).
So a hack is we know that 20% times 5 =100% and 40 divided by 2=20 so
50=40%
divide both sides by 2
25=20%
20 times 5=100 so
multiply both sides by 5
125=100%
(4,-16) factor 3/4
3/4 ×4=3 , -16×3/4= -12
B' (3,-12)
