The endpoints of bar(AB) have coordinates are A(9, 8) and B(-1, -2), so the midpoint is simply the average of x- component of both coordinates and the average of y- component of both coordinates.
A=(x₁, y₁)=(9, 8)
B=(x₂, y₂)=(-1, -2)
The midpoint formula is given below;
is the midpoint of bar(AB).

18, you have 3 choices for the bottom because you can't use the small one, 3 choices for the next because you can now use the small one, 2 for the next and finally 1. You multiply all of them to get 18
Answer:

Step-by-step explanation:
Since this is mathematics, significant figures are not necessary. Thus, we can just take 0.58 and delete the 0s. Now,
