You are right. Transitivity means, that:
if a = b and b = c, then a = c
(here a = x, b=5 and c = y).
Answer:
The first and last graph.

- Solving systems of equations graphically
Step-by-step explanation:
In order for a systems of equations to have a solution set, the 2 graphs must intersect at at least 1 point. Here, we see that graphs 1 and 5 do not intersect each other at all.
Therefore, the rest of the graphs have solutions and #1 and #5 do no have any solutions.

8 * 3 = 24
3 * 8 = 24
You find the mean absolute deviation by first finding the mean, and then subtracting all the values in the data set from that, creating a new data set, and then you find the mean of this new data set.
Example:
3, 2, 5, 9, 4
Mean(add them all, divide by how many there are): (3 + 2 + 5 + 9 + 4)/5 = 4.6
Subtract 4.6 from/to all the values:
4.6 - 3 = 1.6
4.6 - 2 = 2.6
5 - 4.6 = 0.4
9 - 4.6 = 4.4
4.6 - 4 = 0.6
Find the mean of these values:
(1.6 + 2.6 + 0.4 + 4.4 + 0.6)/5 = 1.92
So the mean absolute deviation is 1.92.
