Answer:
The coordinates of the image point will be (-2,-4).
Step-by-step explanation:
The reflection of the point (2,-4) over the y-axis is to be determined.
Now, as the reflecting mirror is the y-axis, then the y-coordinate of the reflecting point will not change.
So, the image point will have coordinates (h,-4).
Now, after the reflection over the y-axis, the x-coordinate of the image point will change the sign only compared to the original point.
Therefore, the coordinates of the image point will be (-2,-4). (Answer)
 
        
             
        
        
        
Answer:
Step-by-step explanation:
no of days                                                   no of men
30                                                                         20
24                                                                             20
30/24=x/20
24 x=30*20
24x=600
x=600/24
x=25
therefore  5 more men are needed to complete the work in 24 days
