Answer: A
<u>Step-by-step explanation:</u>
Create a table for y = x when x ≤ -1 and y = -x when x > 1.
Then, compare the coordinates from the table to the graph. The first graph, <em>which I consider to be graph A</em>, matches the coordinates from the table.
c. must be renewed periodically
hope this helps!!

Answer:
Step-by-step explanation:
x + z + y = 60
- x + z + y = -6 <-- (x - z = y + 6)
x + 3z + y = 40
<em>cancel out the two equations (z minus each other and y minus each other)</em>
x + z + y = 60
- -x + z + y = -6
