First fold = .02
2nd fold = .04
3rd fold = .08
4th fold = .16
5th fold = .32
6th fold = .64 cm
Check the picture below.
well, g(x) + 1 is simply a vertical shift upwards of 1 unit, if the vertex before that had a y-coordinate of 4, then later on became 4+1 or 5, so the new vertex is simply (3 , 5).
The standard form of a line:
.
The point-slope form: 
We have the point (3, -1) and the slope m = -1. Substitute:

<em>add x to both sides</em>
<em>subtract 1 from both sides</em>

Answer: A and E
Step-by-step explanation: since the question says boys to girls and not girls to boys we assume the first number in the ratio is boys. This makes A correct 3 boys for every 2 girls. And 3+2 is 5 so for every 5 students there are 2 girls because you add the 3 boys
I would say D, determine if it can be factored by grouping (sorry, I forgot to put in the answer here).
