x=-b+√b²-4ac/2a
x=-6<u>+</u> √(-6)²-4(9)(1)/2(9)
x=-6<u>+</u> √36-36/18
"x=-1/3 is correct answer."
Hope this helps!
Thanks!

Answer:

Step-by-step explanation:
x - 3y + 8x - 7y = 5 + 6
9x - 10y = 11
9x - 10y + 10y = 11 + 10y
9x = 11 + 10y
9x ÷ 9 = 11 + 10y ÷ 9

A. is a monomial because it's only one term.
For example: if there are two tens and 15 ones, you could take another ten out of the ones. this makes the adding less complicated
I think this is the binomial combination distribution function.
On a Ti-84 plus it would be binomcdf(12,0.5,1)
