C r = (n!)/(r!(n-r)!)
9 C 3 = (9!)/(3!*(9-3)!)
9 C 3 = (9!)/(3!*6!)
9 C 3 = (9*8*7*6!)/(3!*6!)
9 C 3 = (9*8*7)/(3!)
9 C 3 = (9*8*7)/(3*2*1)
9 C 3 = (504)/(6) 9 C 3 = 84

What is the slope of the line shown below?​
Sophie [7]

Hi there!

\large\boxed{slope = \frac{1}{5}}

Use slope formula to solve for the slope of the line:

slope = \frac{y_{2}-y_{1}  }{x_{2} -x_{1} }

Plug in points into the equation. We can use the points (0, -10) and (25, -5):

slope = \frac{-5-(-10)  }{25 -0 } = \frac{5}{25} = \frac{1}{5}

Find all of the points on the x-axis which are 6 units from the point (−1, 1).
anyanavicka [17]
All the points that are 6 units from (-1, 1) are those on the circle
  (x+1)^2 +(y-1)^2 = 36

For y=0, the two points of interest satisfy
  (x+1)^2 +1 = 36
  (x+1)^2 = 35 . . . . . . subtract 1
  x+1 = ±√35
  x = -1±√35

The points you seek are (-1-√35, 0) and (-1+√35, 0), about (-6.916, 0) and (4.916, 0).
