The correct answer is A.

In geometry, a set of points in space are coplanar if there exists a geometric plane that contains them all. For example, three points are always coplanar, and if the points are distinct and non-collinear, the plane they determine is unique. In other words, to be coplanar, all points have to lie in the same plane. Point d is not in the plane, therefore all points except d, are non coplanar.

How many solutions does the system have?<br> y = -3x +9<br> 3y = -9x + 9
Trava [24]

Answer:

{y,x} = {0,1}

Step-by-step explanation:

// Solve equation [1] for the variable  y

 [1]    y = 3x - 3

// Plug this in for variable  y  in equation [2]

  [2]    -3•(3x-3) - 9x = -9

  [2]     - 18x = -18

// Solve equation [2] for the variable  x

  [2]    18x = 18

  [2]    x = 1

// By now we know this much :

   y = 3x-3

   x = 1

// Use the  x  value to solve for  y

   y = 3(1)-3 = 0

A bowl contains 25 balls numbered 1 to 25. A ball is drawn and its number is noted. Without replacing the first ball, another ba
bazaltina [42]

13  balls are odd in 25

1st pick = 13/25 probability of picking an odd

2nd pick = 12/24 = 1/2 probability

13/25 x 1/2 = 13/50 probability

Answer would be 13/50
