Step-by-step explanation:
Answer E is the only one that is close 
 
        
                    
             
        
        
        
Let x be the old price 
X= 1200$
The price decreased 20% after 1 year to become price y : 
Y= 0.8x
 = 0.8 (1200)
 = 960$
In the year after y also decreased 20% to be price y’:
Y’= 0.8y
 = 0.8 (960)
 = 768 $
The price y’ then decreased 20% to become price y’’:
Y’’ = 0.8 y’
 = 0.8 (768)
 = 614.4 $
Then the price will be 614.4 $ after 3 years 
        
                    
             
        
        
        
Step-by-step explanation:
Step 1: Plot the points
L(1,2)
M(0,-1)
J(1,-2)
K(2,-1) 
Step 2: Multiply each point by 5.
and record thise points so we have 
L(5,10)
M(0,-5)
J(5,-10)
K(10,-5)
Step 3: Plot those points.
 
        
                    
             
        
        
        
It depends on which triangle it actually is
        
             
        
        
        
Recall that tanA = sinA / cosA.
Therefore, tanA = (3/5) / (4/5) = 3/4.
