Answer:
1. (4,6)
2. (-1, 8)
3. Not enough information given.
Step-by-step explanation:
1. Reflecting the point over the y-axis will place the point (-4,6) 4 units on the other side of the axis. This would place it at (4,6) without changing the y-coordinate.
2. Reflections across the line y=x means y and x trade places. This will result in the point (8,-1) becoming (-1,8).
3. Not enough information about the shape is given. Need to know where it is now to know where it will go.
Answer:
The answer would be 10 tickets because 400 divided by 40 equals 10
Step-by-step explanation:
The possible permutations are 6P3 which is 120. Out of those there are 7 ways to get 6 with three dice. So P(6)=7/120
1+8=3r
9=3r
Both divided by 3
3=r
