Answer:
Step-by-step explanation:
This construction shows how to draw the perpendicular bisector of a given line segment with compass and straightedge or ruler. This both bisects the segment (divides it into two equal parts, and is perpendicular to it. It finds the midpoint of the given line segment.
Answer:
(-2,6)
Step-by-step explanation:
The solution to the system of equations should be true for both equations. This means that if you substitute -2 into both equations, you should get 6 as the y value for both equations.
They gave you a graph, and to find the solution from the graph, you just look at which point is shared by both lines, or at which point both lines intersect.
There is also a mathematical way to do it using substitution and elimination, but you should master the graphing method first before moving onto those.
Electricity wasn't the only energy cost. also look at logs for fire. being that they were bought for fire it is using heat energy. there for making the total energy cost the highest. only look at what is energy cost toward the overall bill.
