X and y are switched and y times -1 so
reflection across the x=y line (identiy line)
and since the x place it times -1, that is a reflection across y axis
so reflection across x=y line and y axis
        
                    
             
        
        
        
Answer:
I just solved a question similar to this 
Let's understand it 
It's saying she got 660 or it is that her weekly pay is 660 
So now let weekly pay which is P be 660 
Hence the formulae is given 
It's 480 + 18 (h – 30) = 660 
Now its just boring calculation 
If you mark it brainleist I will do the calculation for you wink wink 
Never mind 
480 + 18 (h – 30) = 660
18 (h – 30) = 660-480
18 (h – 30) = 120
(h – 30) = 120/18
(h – 30) = 6.6
h = 6.6+30
h= 36.6
So dam the Judy lady worked for 36.6 hours

David purchased some cookies at the cost of 
5 for $4 (5/4=1.25) and 
sold them at 4 for $5(4/5=0.80). 
To find cost per cookie subtract 1.25-0.80=0.45
David made a profit of $180 in total ( divide profit per cookie cost: 180/0.45= 400)
How many cookies did David purchase to make that much money?
He needed to make 400 cookie to make the profit of $180.
