The perpendicular bisector of the segment passes through the midpoint of this segment. Thus, we will initially find the midpoint P:

Now, we will calculate the slope of the segment support line (r). After this, we will use the fact that the perpendicular bisector (p) is perpendicular to r:


We can calculate the equation of
p by using its slope and its point P:
Answer 3,5,7
Step-by-step explanation:
If you want to make it so that you work most of the hours on the first 4 days, you should work 5 hours. 5*4=20, so 1 hour would be left over on the 5th day.
If we are only using the values in the table, then the answer is D.
This is because the highest value of y is 40 and the lowest is 37.75. So we must know that y is between these two.
However, if we are using this table as a long term model, then C is the correct answer. We know there is 40 to start and it will continue going down until it hits 0.
