Your question is poorly formatted; However, the correct question is:

Point  A  ( 3 , 4 )  and point  M  (5.5,0) is the midpoint of point  A and point B. Determine the coordinates of B

The coordinates of B is (8,-4)

Step-by-step explanation:

Given

Point  A  ( 3 , 4 )

Point  M  (5.5,0)

Required

Determine B

Since, M is the midpoint;

We'll solve this question using the following formula;

Where and

Substitute values for x, y, x1 and y1 in the above formula;

This gives

By direct comparison, we have

 and

Solving

Multiply both sides by 2

Subtract 3 from both sides

Solving

Multiply both sides by 2

Subtract 4 from both sides

Hence;

The coordinates of B is (8,-4)
