Eight blood types are shown by the eight regions of the Venn diagram shown here. Each circle represents one of three antigens: A, B or Rh. If A and B are both absent, the blood type is O. If Rh is present, the blood type is positive; otherwise, it is negative. The following table represents the blood types of 150 people. How many people have blood type O+?

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
