Find the midpoint of the line segment joining the points P1 and P2.
ludmilkaskok [199]

Formula for midpoint between two points is M(x,y)

x=(x1+x2)/2 and y=(y1+y2)/2

In our case (x1,y1)=(m,b) and (x2,y2)=(0,0)

x=(m+0)/2=m/2 and y=(b+0)/2=b/2     M(m/2,b/2)

Good luck!!!

4-20. When Susan's brother went to college, she and her two sisters evenly
Zigmanuir [339]

Each sibling got 1 poster, 8 CDS and 72 books.

<h3>How the belongings were divided </h3>

Since the belongings were divided equally, each sibling would get the same amount of belongings. In order to determine the belongings each person got, we would divide each possession by 3.

  • Number of poster each person got = 3/3 = 1
  • Number of books each person got = 216
  • Number of CDs each person got = 24 / 3 = 8
