Answer:
8
Step-by-step explanation:
There are less people on the 8.
5 million = 5*10^6
40% * x = 5*10^6
x = (5*10^6)/0.4 = (5/0.4)*10^6 = 12.5 * 10^6 = 1.25 *10^7
If you have a graphing calculator I think you can enter in the points to get the answer to this.
Convert the equations to slope/intercept form:-
4x + 4y = 1
4y = -4x + 1
y = -1x + 1/4 The slope of this line is -1
x + y = -8
y = -1x - 8 This also has a slope of -1
So B is true. The lines are parallel.
