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)
The first two (top two) choices should be selected. The midpoint of a line segment divides the line segment into two congruent parts, so the first is true by the definition of midpoint. The whole is the sum of its parts; Adding the two smaller segments will always equal the whole.
The answer is B.
The answer isn’t A because there are 25 cents in a quarter, not 10 cents.
The answer isn’t C because to pay for something you need to have greater or equal amount of cash.
The answer isn’t D because the letters don’t have a value, as they should be 10d and 25q.
Therefore, the answer is B.
7(h-4) = 2h + 17 distribute to get:
7h - 28 = 2h + 17 subtract 2h from both sides to get:
5h - 28 = 17 add 28 to both sides to get:
5h = 45 divide 5 from both sides to get:
h = 9
