Answer:
The length of the segment F'G' is 7.
Step-by-step explanation:
From Linear Algebra we define reflection across the y-axis as follows:
 ,
,  (Eq. 1)
 (Eq. 1)
In addition, we get this translation formula from the statement of the problem: 
 ,
,  (Eq. 2)
 (Eq. 2)
Where:
 - Original point, dimensionless.
 - Original point, dimensionless.
 - Transformed point, dimensionless.
 - Transformed point, dimensionless.
If we know that  and
 and  , then we proceed to make all needed operations:
, then we proceed to make all needed operations:
Translation




Reflection


Lastly, we calculate the length of the segment F'G' by Pythagorean Theorem:
![F'G' = \sqrt{(5-5)^{2}+[(-1)-6]^{2}}](https://tex.z-dn.net/?f=F%27G%27%20%3D%20%5Csqrt%7B%285-5%29%5E%7B2%7D%2B%5B%28-1%29-6%5D%5E%7B2%7D%7D)

The length of the segment F'G' is 7.
 
        
             
        
        
        
Answer:
where is the figure?
Step-by-step explanation:
 
        
             
        
        
        
If e is between them, then the distances DE and EF add to the total, DF. So the answer is just 27 + 34 which is 61, A
        
             
        
        
        
1580 I assume srry if it is incorrect 
        
                    
             
        
        
        
There are two sides (heads and tails). So one head would be 1/2, and one tail would also be 1/2.
