<u>First Method</u> :
8P5 = 8 × 7 × 6 × 5 × 4
        = 6720

Answer:
4 hours and 45 minutes.
Step-by-step explanation:
Since Christchurch is 2 hours ahead of Sydney, you subtract 2 from 12:45 and get 10:45 so then, you determine the difference between 10:45 and 6:00 AM and it results in 4.75 hours or 4 hours and 45 minutes
 
        
             
        
        
        
Answer:
D. y = { -x + 2 x ≥ 1}
           { x + 1  x < 1}
Step-by-step explanation:
First is to eliminate A and C, why?
This is because of the end points shown on the graph.
As shown, if you look at the point of (2,1) it is black, this means that not only is it closed but it is also means ≤ or ≥ symbol.
You are now left with B and D
The difference between these two is the symbols; they are facing the opposite directions.
While B says x ≤ 1, and x > 1
While D says x ≥ 1, and x < 1
The direction of the symbols depends on the direction of the lines and what is part of it (some what like a shaded area)
 So you answer would be D
