Answer:
$33600
Step-by-step explanation:
Let x = original car price
Since it is a 25% profit that means we multiply x by 1.25
1.25x = 42000
Divide both sides by 1.25
1.25x/1.25 = 42000/1.25
x = 33600
 
        
             
        
        
        
Step-by-step explanation:
x	y
−3	0
 −1 −2 
2 −5 
6 −9 is a nonlinear
because when you plot the points given x=-3 y=0 and x=-1 y=-2 are found in the 3rd quadrant and the rest are found in the 4th quadrant.
which will not make the points linear
Hope this will help
 
        
             
        
        
        
Change the first to a decimal
15 2/5 = 15 4/10 = 15.4 miles
15.4 miles 
------------
2.1 hours
7.33333333(repeating) miles/hour
7 1/3 miles per hour
 
        
             
        
        
        
4y^2 + 2 - 2 = 38 - 2 (subtract both side by 2)
4y^2 = 36
Divide by 4:
y^2 = 9
y = 
y = 3
 
        
                    
             
        
        
        
It is already in decimal form............
