Answer:
1. -2=-x - 9, 7=-x, -7=x
2. -1=-x - 9, 8=-x, -8=x
3. 0=-x - 9, 9=-x, -9=x
4. 1=-x - 9, 10=-x, -10=x
5. 2=-x - 9, 11=-x, -11=x
33.3%
Since we are given that it is an even number, we know there is only 3 options (2, 4, 6). Since only one of them is an even number, we know that we need the fraction 1/3 or 33.3% for a probability.
Perpendicular lines will have negative reciprocal slopes
B. y = -4x+ 5 and y = 1/4x + 4
D. y = x + 4 and y = -x + 4
E. y = -3 and x = -3
Answer:
I'm not 100 percent sure but but part a is
0 0
6 18
12 36
and then part b is letter A

The wording of this question is a bit confusing... You can't write a sequence in sigma notation, but rather a series or sum. I think the question is asking you to write the sum of the sequence,

which would be

in sigma notation.
To do this, notice that the denominator in each term is a power of 2, starting with
and ending with
. So in sigma notation, this series is
