Find the midpoint between -1/11 and 9/11. Pls, help asap! :)

(4,11) is the midpoint :)

Step-by-step explanation:

it would be

(-1,11), (9,11)

-1+9/2, 11+11/2

8/2, 22/2

4,11

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
