Answer:

Step-by-step explanation:

Hi!

Here is the formula for point slope form: y-y1=m(x-x1)

Our slope in this case is 5, and our points are (1, 9). 1(x1) and 9(y1)

So, if we substitute our given data into the formula, here is what we will get.

y-9=5(x-1)

Thus, our answer should be:

y-9=5(x-1)

I hope this helps!

hjlf

Answer:

  • 32598720

Step-by-step explanation:

<u>Combination for the school government requires:</u>

  • 5 out of 8 seniors = 8! / 3!5! = 6*7*8/2*3 = 7*8 = 56
  • 4 out of 9 juniors = 9! / 4!5! = 6*7*8*9/2*3*4= 7*2*9 = 126
  • 3 out of 12 sophomores = 12! / 3!9! = 10*11*12/2*3 = 10*11*2 = 220
  • 2 out of 7 fishermen = 7! / 2!5! = 6*7/2 = 21

<u>So number of total ways is:</u>

  • 56*126*220*21 = 32598720

Help asappppopppppppp don’t play games IF u don’t know skip

I’m not completely sure, but I would say about 3/5 because of the fact that the X is not directly in the middle, so it can’t be 1/2 but it’s very close to the middle which could make it possible that it is 3/5?

B^2=256

\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}

B=\sqrt{256},\:B=-\sqrt{256}

\sqrt{256}

\mathrm{Factor\:the\:number:\:}\:256=16^2

=\sqrt{16^2}

=16

-\sqrt{256} =-16

B=16,\:B=-16
