The endpoints of GH are G(3,3) and H(-7,7). Find the coordinates of the midpoint M.

sesenic [268]

Step-by-step explanation:

Hey there!!

You can simply use midpoint formulae to find midpoint of the coordinates.

Here, Given that;

G(3,3) and H(-7,7).

Using midpoint formulae,

$midpoint \: of \: gh = (\frac{x1 + x2}{2} ,\frac{y1 + y2}{2}$ )

$midpoint \: of \: gh = (\frac{3 - 7}{2} ,\frac{3 + 7}{2}$ )

After simplifying it we get,

= (-2,5).

Therefore, midpoint of GH is M(-2,5).

Hope it helps....

If A = -4m + 1, and B = 7m - 9, what is the value of A + B, in simplest form?

Natasha2012 [34]

The ore the answer is B. Why?

Because (-4m+1) + (7m-9) = 3m - 8

You add -4m and 7m and get 3m and the only answer that has a POSITIVE 3m is B.

Anyways, you still have to check it. 1+(-9) is -8. So A+B = 3m - 8
