Assuming the order of selection doesn't matter:

\displaystyle \binom{9}{3}=\dfrac{9!}{3!6!}=\dfrac{7\cdot8\cdot9}{2\cdot3}=84

WILL MARK BRAINLIEST!!
adoni [48]

Answer:

solution: x= 0.273, y= 1.909.

Step-by-step explanation:

  • given system of linear equations : x+3y=64x−6y=6
  • these can also be splitted or written individually as:

x+3y=6     &   64x−6y=6

  • the first equation can also be written as, y=2-\frac{x}{3}

so,  it is line with slope : -1/3 and y-intercept :2

  • the second equation can also be written as, y=\frac{32x}{3} -1

so,  it is line with slope : 32/3 and y-intercept :   -1

  • now we can easily draw graphs for these equations using the above interpretation.
  • graph is in the attachment.
  • so, the solution is:  x= 0.273, y= 1.909.
