Because a polygon is a shape that has equal sides and no curves.
        
                    
             
        
        
        
Ok so the first one is 225 miles but i can't do the graph
and i'm not great at math so give me a bit
        
             
        
        
        
Answer:
 -2.25
Step-by-step explanation:
9(1-x) = 27Y
9-9x =27y
-9x -27y = -9  multiply all terms by -1
9x +27y =9   equation (1)
x-y= -11/2 equation (2)
by solving 2 equations 
x= -3.875
y= 1.625
∴ x+ y = 1.625 +(-3.875) = -2.25
 
        
                    
             
        
        
        
2 4/5 I believe is the least value.
        
             
        
        
        
Answer:
   5.  (x, y) ⇒ (x +5, y +1)
   6.  (x, y) ⇒ (x +4, y -1)
Step-by-step explanation:
A translation rule will generally have the form ...
   (x, y) ⇒ (x +h, y +k)
where (h, k) is the horizontal and vertical distance to the right and up that the figure is being translated.d
5) The image is 5 units right and 1 unit up from the original, so in the above formula, (h, k) = (5, 1) and the translation rule is ...
   (x, y) ⇒ (x +5, y +1)
__
6) The image is 4 units right and 1 unit down from the original, so (h, k) = (4, -1) and the transformation rule is ...
   (x, y) ⇒ (x +4, y -1)
