Find the midpoint of the segment with the endpoints: (-4,5) and (7,-9)
kati45 [8]

Answer:

Let's denote: A(-4, 5), B(7, -9).

If P(x, y) is the midpoint of AB, then we have:

x = (-4 + 7)/2 =3/2

y = (5 + (-9))/2 = -2

=> P(3/2, -2)

Hope this helps!

Which expression is not equivalent to 8 + (n - 4)?<br> n +4<br> (8 + n) - 4<br> 12 + n<br> (8-4) +n
Alenkasestr [34]

Answer:

12+n

Step-by-step explanation:

8+n-4 = n+4

n+4 = n+4 (Can not be simplified).

(8+n)-4 = n+4

12+n = 12+n (Can not be simplified).

(8-4)+n = n+4

So the answer would be 12+n because it does not equal n+4.
