For Q2 it is just a simple matter of using a tree diagram for each possible outcome. So there are 4 black balls (B) and 2 white (W) and by using a tree diagram of the possible outcomes it comes to a 3 out of 5 points go to player 1 if B was drawn first and 2 go to player 2. If W was drawn first though, then player 1 gets 1 out of 5 points and 4 goes to player 2 and if you add up the probabilities at the end it comes to player 1 having a 14 out of 30 chance and player 2 having a 16 out of 30 chance therefore player 2 would have a better chance at winning and it isn't a fair game
Answer: (3 x --- 2) (6x--- 1)
Step-by-step explanation: Common factors from the two pairs
Rewrite in factored formed
1. Substitute y=-x+2 into x-3y=-18:
x-3(-x+2)=-18,
x+3x-6=-18,
x+3x=-18+6,
4x=-12,
x=-3.
Then y=-(-3)+2=3+2=5.
2. The graphs of two equations you can see in attached diagram. Common point (the point of intersection) represents the solution of the system of two equations.
Answer: (-3,5) or x=-3, y=5.
