(I’m like 99% sure)
Answer:
A
Step-by-step explanation:
Well automatically we can eliminate B and D because they make no sense whatsoever. So that leaves us with A and C. A is telling us to find the mean so it has to be that one. So, with procces of elimination the answer has to be A. I know this because the owner needs to find an average to see how many bottles he will have sold daily. ;) Your very much welcome
The interval over which the given quadratic equation decreases is: x ∈ (5, ∞).
<h3>How to find the interval of quadratic functions?</h3>
Usually a quadratic graph function decreases either when moving from left to right or moving downwards.
In the given graph, we can see that the coordinate of the vertex is (5, 4) after which the curve goes in the downward direction.
Thus, for the values of x greater than 5, the function decreases and so we conclude that the interval in which the quadratic equation decreases is: (5, ∞).

Answer:
Bryan walks faster
Bryan was farther away from home when he started walking.
Step-by-step explanation:
Given the following :
Brendon's distance in feet from home 'y' in relation to the number of minutes walked 'x'
y = 7,920 − 270x
For bryan:
Minutes (x) - - - 0 - - - - - 15
Feet ( y) - - 8000 - - - 3800
General form of a linear equation :
y = mx + C
m = gradient / slope
m = (y2 - y1) / (x2 - x1)
m = (3800 - 8000) / (15 - 0)
m = -4200 / 15 = - 280
Intercept 'c' = 8000 (where line intersect the y axis), (since y = 8000, when x = 0)
Therefore,
Bryan's model:
y = 8000 - 280x
Comparing both functions :
Bryan has a greater speed ( from the gradient)
Bryan was farther away from home when he started walking ( intercept )
