Let A represent the value of the car after each year.
A= initial value (P)×(1+percent increase(r)) ^time
A=P×(1+r)^t
A=18710×(1+(-12%))^8
A=18710×(1-12%)^8
A=18710×(1-0.12)^8
A=18710×(0.88)^8
A= 6728.7619591115
The best approximation is 6729
Therefore the value of the car will be about $6729 after 8 years

Answer: Answer is 3 
BC        6
------ = ------
XY         3
Step-by-step explanation:
The statements below can be used to prove that the triangles are similar.
On a coordinate plane, right triangles A B C and X Y Z are shown. Y Z is 3 units long and B C is 6 units long.  
A B Over X Y = 4 Over 2 
?  
A C Over X Z = 52 Over 13  
△ABC ~ △XYZ by the SSS similarity theorem.
Which mathematical statement is missing?
1.   Y Z Over B C = 6 Over 3  
2.  ∠B ≅ ∠Y
3.  B C Over Y Z = 6 Over 3  
4.  ∠B ≅ ∠Z
 
        
                    
             
        
        
        
Set up a fraction use one radical sign divide the radicans simplify if neccessary 
        
                    
             
        
        
        
Answer:
x=16
Step-by-step explanation:
y = 1/2 x -3
Let y =5
5 = 1/2 x -3
Add 3 to each side
5+3 = 1/2 x -3+3
8 = 1/2x 
Multiply each side by 2
8*2 = 1/2x*2
16 =x
