Answer: the distance between the two points in Decimal Form is 9.899
X = 7
5 + x can also be written as 5 + 7
5 + 7 = 12
It doesnt say how many she buys at the coin show so we dont know but its going to be more than 6
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?
