Answer:
Step-by-step explanation:
Use the midpoint formula to solve:

We know the midpoint and one set of coordinates, so filling those in:

Since the -7 is the x coordinate of the midpoint, we set the x part of the equation equal to -7 and solve for x, and then do the same for y. The 2 equations are:
and
We solve each one of these to get the x and y coordinates of the other endpoint. In both cases, multiply both sides of the equations by 2 and then solve by either adding or subtracting.
-14 = x - 19 so
5 = x
16 = y + 30 so
-14 = y
The coordinates of the other endpoint are (5, -14)
There are 10/9 cups of cinnamon in 1 pound of spice mix
and if you wanna convert the improper fraction to a mixed number it will be 11/9
(1/2)^2 = 1/4
2-2/3 = 6/3 - 2/3 = 4/3
OK so:
(1/2)^2 - 6(2-2/3) = 1/4 - 6(4/3)
= 1/4 - 8
= 1/4 - 32/4
= -31/4
No, because the 9 pounds would cost 22.5, and that is 5 cents more than he has
