Answer: (3, -1)</h3>
===============================================
Explanation:
The midpoint formula is 
This basically says to add the corresponding coordinates and divide by 2.
The given points (2,5) and (4,-7) have x coordinates of 2 and 4. They add to 2+4 = 6, and then that result cuts in half to 6/2 = 3. The x coordinate of the midpoint is 3.
The y coordinate of the midpoint is y = -1 since adding the y coordinates of the given points leads to 5+(-7) = -2 which cuts in half to -1.
So overall the midpoint is located at (3, -1)
Answer:
Your answer is 30.

4 = -6w + 8(w+2) is an equation, and your job is to "Find the value of w that satisfies this equation."
Perform the indicated multiplication:
4 = -6w + 8w + 16. This becomes:
4 = 2w + 16, which in turn becomes 2w = -14. Thus, w = -7 (answer)
