We want the final coordinate of K to become (-3,1). If you reflect across the y-axis, you transform

So, we need to move K to (3,1), and then reflect it across the y-axis. Since K starts at (-1,4), we have to move it 4 units to the right and 3 units down.
 
        
             
        
        
        
(x^3 - y^3)(x^3 + y^3)
You can get this by factoring based on the a^2 - b^2 model

     90 Miles                                 45 Miles                  
      2 Hours                                   1 Hour     
Answer:  <u><em>The Train  travels 45 miles in one hour.</em></u> 
How i got the answer? I divied the 90 by 2 because we already know the miles/hour for 2 hours and we need 1 hour.
