The line of reflection is x = 4
It's easier I think to take it and go "what can I add together than makes 17, yet multiplies to 28"
although, I don't think this is a perfect square, either
(x+7)(3x-4) = 0
heres the factored form, but I couldn't even begin to say how I got it, all I know is that it works
A.) y = x - 4
b.) y = 8x
c.) y = 12x - 4
d.) y = x - 4
I am like 90% positive this is right but don’t count on it. I tried.
So your TOTAL number is 30, and they're saying only 5/6 of that TOTAL number showed up. So by a simply multiplication you'll find how many showed up:
30 x 5/6 = 25
