37. a group of people share equally in a $20,000,000 lottery. before
the money is divided, two more winning ticket holders are
declared. as a result, each person's share is reduced by $500,000.
how many people were in the original group of winners?

20 people

Step-by-step explanation:

You do 20,000,000 divided by 2 in a calculator, which is 10,000,000 then divide it by 500,000 to get 20

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

i believe that the answer is

b. y-1=-2(x-4)

hope this !
