If M (6,8) is the midpoint of line segment AB, and if A has coordinates (2,3) , find the coordinates of B.

sveticcg [70]

Graphing is one way to do the problem.But sometimes, graphing it is hard to do.So here’s an algebraic method.
If M(m1, m2) is the midpoint of two points A(x1, y1) and B(x2, y2),then m1 = (x1 + x2)/2 and m2 = (y1 + y2)/2.In other words, the x-coordinate of the midpointis the average of the x-coordinates of the two points,and the y-coordinate of the midpointis the average of the y-coordinates of the two points.
Let B have coordinates (x2, y2) in our problem.Then we have that 6 = (2 + x2)/2 and 8 = (3 + y2)/2.
Solving for the coordinates gives x2 = 10, y2 = 13

if the total income generated from gasoline for AER was $408 million , how much would be the cost of a gallon of gasoline

givi [52]

I found the pie chart that should accompany this problem, as well as, the choices of answer for this problem.

A $16
B $18
C $20
D $22
E $24

Total production from crude oil: 60 million barrels
Gasoline production: 34%

60 million barrels * 34% = 20,400,000

Total income: $408 million

408,000,000 / 20,400,000 = $20 choice C.
