Answer:

Step-by-step explanation:
Co-ordinates of point A = ( -7 , 1 )
Co-ordinates of point M = ( -2 , 2 )
Let the co-ordinates of point B be ( x , y )
A ( -7 , 1 )
( x1 , y1 )
B ( x , y )
( x2 , y2 )
Now,
Midpoint = 
⇒
Finding the value of x :
⇒
Do cross multiplication
⇒
⇒
⇒
⇒
Now, finding the value of y
⇒
Do cross multiplication
⇒
⇒
⇒
⇒
Hence, The co-ordinates of point B = ( 3 , 3 )
Hope I helped!

Answer: 
Step-by-step explanation:
To solve for w, we want to isolate the variable.
[add both sides by 2 and w]
[convert to same denominator]
[add]
[multiply both sides by 6/13]

Now we know that
.
