This gives you three simultaneous equations:
6 = a + c
7 = 4a + c
1 = c
<u>c = 1
</u><u /><u />
If c =1,
6 = a + 1
<u>a = 5
</u><u /><u />
This doesn't work in the second equation, so the quadratic that goes through these points is not in the form y = ax^2 + bx + c
Was there supposed to be a b in the equation?
2(4-d+2d)=12
8-2d+4d=12
8+2d=12
2d=4
d=2
If you do 84 x 5 then you have 420 people lower than you
Answer:
7/16
