Answer:3/19
Step-by-step explanation:
5/19 - 2/19 = 3/19
The answer is A so yeaaaaaa
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,
.
(2, 8)
Because you cannot divide by 0, which 2 would do to the bottom.
