Answer:
yes, yes, no
Step-by-step explanation:
1. L= i + 2j +k; P = -3i + j + k, line lies on one another at k
2. L =i + 2j + k and P = 6i -3j + k, the lines lie on one another at k
3. P = ai + bj and -2bi +2aj + (a+b) k
Holly has 20 balls, and there are 100 balls in total.
So there are 100-20 = 80 balls left.
Alex had 2 * the amount Holly had, which is 20.
So Alex has 20 * 2 = 40 balls.
Together, they have 60 balls.
Which means 100-60 = 40. So Ben has 40 balls.
Check:
Holly: 20
Alex: 40
Ben: 40
Add them: 20 + 40 + 40 = 100

Answer: The 9th term is 6561
Step-by-step explanation:
The geometric sequences have the following formula
Where 
is the first term of the sequence and r is the common ratio between the consecutive terms of the sequence
In this case the sequence is 1 -3 9 -27
So 
Observe that the common ratio r is:
So the formula is:
We want to find
