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 )
This is really simple math. You just put the two over each other:
25.65+14.23= 39.88. The rounded answer would be 39.9

So whoever asked the question forgot the factor 2!!!
Or did I miss anything??
Answer:
The option is first one that is
Step-by-step explanation:
Given:
After negative exponent eliminated we get
Negative exponent :
The variable containing negative powers. Here the variable( n⁻¹) is negative exponent.
Law of indices
The Lagrangian,
has critical points where its partial derivatives vanish:
tells us , so that
Then with , we get
and tells us
Then there are two critical points, . The critical point with the negative -coordinates gives the maximum value, .
