Answer:
See below 
Step-by-step explanation:
Figure A has a square cut out into it as figure B has a trapezoid cut out into it. 
A reflection is mirroring an image, this means that the image must be identical to its reflected image. 
Because figure A and B have different shapes cut into it they are not identical and can therefore not be reflections. 
 
        
                    
             
        
        
        
Answer:
Set it up as a table and insert the numbers one by one
 
        
             
        
        
        
Answer:
slope is -2 and the y-intercept is 12 
Step-by-step explanation:
a key thing to remember: x is always equal to 0 when finding the y-intercept. 
so if you look at the table for where 0 is, you get the point (0,12) meaning the y-intercept is 12. 
to find the slope use the equation: slope= change in y/change in x
you can use any two points to find this. 
lets take the points of the x-intercept (6,0) and the y-intercept (0,12) 
12-0/0-6 
12/-6
-2 = slope 
 
        
             
        
        
        
X=20
180-77=103
so then simplify (6x-17)=103
6x=120
x=20
