The coordinates of the midpoint of the segment given its endpoints
P(-3,-7) and Q(3,5) is the midpoint of the given segment is (0,-6).
What is a midpoint ?
The midpoint of a line segment divides the line segment into two equal parts.
According to the given question
Co-ordinate of two endpoints are given and we have to find the co-ordinate of the midpoints.
Assuming co-ordinates of the midpoint is (x,y)
We know the midpoint formula is given by
x = (x₁ + x₂)/2 and y = (y₁ + y₂)/2
∴ x = (-3 + 3)/2
x = 0/2
x = 0.
And
y = (-7 -5)/2
y = -12/2
y = -6
So the midpoints of the co-ordinates are (0,-6).

Answer:
The correct answer is B. George’s computer is expected to have a value of $25 greater.
Step-by-step explanation:
Since Chelsea bought a computer on Monday for $ 1,300, and its value is predicted to decrease by $ 250 per year, while her brother George also bought a computer on Monday, and the function g (x) = 1,100 - 175x predicts how the value of his computer is expected to change after x years, to determine whose computer is expected to have a greater value when it is 3 years old, and how much greater will it be, the following calculation must be performed:
Chelsea:
1,300 - (250 x 3) = X
1,300 - 750 = X
550 = X
George:
1,100 - (175 x 3) = X
1,100 - 525 = X
575 = X
Therefore, George’s computer is expected to have a value of $ 25 greater.
