Answer
Midpoint = (3, 5.5)
Step by step explanation
Here we have to use the midpoint formula.
Midpoint = (
)
Here the point A = (-1, 8) and B = (7, 3)
x1 = -1, y1 = 8, x2 = 7 and y2 = 3
Now plug in these values into the formula.
Midpoint = (
= (6/2, 11/2)
= (3, 5.5)
Therefore, the midpoint the line segment AB is (3, 5.5)
Thank you.

we can rewrite it as

we can see that 1/4 is in multiple in both terms
so, we can factor it out
so, we get

First slot, 11 options
2nd is 10 (1 less than 1st slot)
3rd is 9
4th is 8
11*10*9*8=7920 different pizzas (assuming you can't order all 1 topping)
