Well your domain is your x and the range is your y 

the relation is a function if 
1) x has a corresponding y 
2) any one x has only one y 

think about when you graph a point  (x, y)  if the same x has two different ys' then the graph will NOT be a function because does not pass the vertical line test. Like (2,4) and (2,-4) could be touched by a vertical line. 
A. is NOT a function because x=6 has multiple y=9, y=10, y=11

B. is a function because x=4 has y=6, x=7 has y=3, x=9 has y=7!!!

C. is NOT not a function because x=5 has two y, y=6 and y=9
D. is NOTa function because x=5 has two y, y=1 and y=8

Aleks [24]
The problem with the question is that 51% of 1009 adults could not have said that their biggest fear was losing vision. The issue with 51% of 1009 is that you wont be left with a whole number, but a decimal instead. You cant have a decimal of a person.

If 10 of the 50 apples are green than what percent of the apples are green
Andrew [12]
So the question here is just simply what percentage is 10 out of 50 correct? You would basically just do 10/50 times 100 which will give you 20 percent as your answer.

34. x - 3 = 8x + 4
      -3 - 4 = 8x - x
      -7 = 7x
      -7/7 = x
      -1 = x

y = x - 3
y = -1 - 3
y = -4

solution is (-1,-4)
===================
35. -6 = -x - 2y
      x = -2y + 6

2 + 5x = -2y
2 + 5(-2y + 6) = -2y
2 - 10y + 30 = -2y
32 = -2y + 10y
32 = 8y
32/8 = y
4 = y

2 + 5x = -2y
2 + 5x = -2(4)
2 + 5x = -8
5x = -8 - 2
5x = -10
x = -10/5
x = -2

solution is (-2,4)
==================
36. 4x + 6y = 2000
       x + y = 410
==================
37. 4x + 6y = 2000
       x + y = 410......multiply by -6
----------------------
4x + 6y = 2000
-6x - 6y = - 2460 (result of multiplying by -6)
--------------------add
-2x = - 460
x = -460/-2
x = 230 <=== tickets in advance
