Answer: point 1 is (-4,-6) point 2 is (-4,8)
Step-by-step explanation:
point D is located at (-4,1) with the x-coordinate being -4 and the y-coordinate being 1 so to get the points 7 units away with the same x-coordinate you:
1. subtract 7 from the y-coordinate in the original point (-4,1) and get (-4,-6) your first point
2. add 7 to the y-coordinate in the original point (-4,1) and get (-4,8) your second point
To get the answer you would have to subtract 23 from both sides and you would get
X+23-23= 63-23
this would leave you with
X= 40

^ means to the power of, problem is that i have a hard time adding the actual symbol.
so when you see ^ when you answer you would have to put it like this:

Answer:
Step-by-step explanation: The expected loss is 50 cents, we know that it is more likely to lose than win. It is therefore difficult to get-50, so the overall difference between the two possibilities is 2, 50/200=1/4, and the probability to win is 1/4, and the probability to lose is 3/4. Since (1/4)*3=3/4, the number of black balls is 3 times the number of white balls, so k=15.
