The ordered pair that represents the halfway point between Mary's home and the grocery store is (1, 4)
The midpoint (a, b) between two linear points 
and 
is calculated as:
On a map, Mary's house is located at (−3, 1) and the grocery store is located at (5, 7).
Substitute these values into the mid-point formulae

Subtract the sum of the known sides from the perimeter to find the length of the missing side.
For this case we have the following function:
y = 1/4 (x + 2) ^ 2 - 7
We derive the equation:
y '= 1/2 (x + 2)
Equaling zero we have:
1/2 (x + 2) = 0
We clear the value of x:
x + 2 = 0
x = -2
Answer:
The equation of the axis of symmetry for the parabola is:
x = -2
For the midpoint, you find the differences in x values and y values then divide them by 2. Like so:
Let's do x first:
(-16-0)/2 = (-16)/2 = -8
So our x coordinate is -8.
Now Y:
(-16)/2 = -8
So our Y coordinate is -8 as well.
So your answer is:
(-8,-8)
Evaluate A² for A = -3.
(-3)² = (-3) * (-3) = 9
Your answer is 9.
If the question is, however, evaluate A2, which is 2A, for A = -3, then the answer is:
2A = 2(-3) = -6.
