The location of point Y is the point -3 on the number line
Here, we want to find the location of Y 
let us say the point 0 represents the origin
The coordinates of point x will be (-9,0) while the coordinates of point z will be (3,0)
To find the location of Y , we proceed to use the midpoint formula as follows;

Thus, we have;
(-9 + 3)/2 , (0 + 0)/2
= -6/2 , 0
= (-3 , 0)
 
        
             
        
        
        
Answer:
12.5 cm
Step-by-step explanation:
0.625km=62500cm. The scale factor is 1:5000. So the distance on the map will be 62500/5000=12.5 cm

Answer:
28x + 7y = 14.
Step-by-step explanation:
Just add the 28x to each side.
 
        
                    
             
        
        
        
The answer is 17
4x3=12
3x2=6
12+6=18
18-1=17
