Answer:
Si el número es x, entonces 1.4x + x = 84,
Entonces 2.4x = 84 yx = 84 / 2.4 = 840/24 = 35. 
El otro número es 84-35 = 49

Answer:
Graph the second equation by finding two data points. By setting first x and then y equal to zero it is possible to find the y intercept on the vertical axis and the x intercept on the horizontal axis. At the point of intersection of the two equations x and y have the same values.
 
        
                    
             
        
        
        
The average between 12.00 and 15.00 seconds 
can be defined in a few different ways.
Way #1:  (speed)
     Average speed =
         (1/2) (the speed at 12 seconds  +  the speed at 15 seconds) .
Way #2:  (speed)
   Average speed = 
       (1/3) (the distance covered between 12.00 and 15.00 seconds)
Way #3:  (velocity)
   Average velocity = 
     (1/3) (distance between location at 12 sec and location at 15 sec)
       in the direction from location at 12 sec to location at 15 sec. 
That's the best we can do with the combination of given and 
not given information in the question.
        
                    
             
        
        
        
Answer:
y=1/2x-1
Step-by-step explanation:
-4y=4-2x
4y=4-2x
y=-1+1/2x
y=1/2x-1
