Answer:

Step-by-step explanation:

b/c she doesn't have to have exactly 50 pounds, she can have any were from 0 to 50 pounds in each suit case. They are not going to charge her more, if she only brings 49 pounds :DDDD It's the same charge up to and including 50 pounds. If she brings 51 pounds then maybe she would get charged more :P But not for 50 pounds or less . :) Make sense?

X+3/ x2-9x+20 A.4 B-3 C-4 D 5 E.3 F -5 apex

serious [3.7K]

Answer:

local minimum at x = -3-2√14
local maximum at x = -3+2√14

Step-by-step explanation:

The first derivative simplifies to ...

d/dx( ) = -(x^2 +6x -47)/(x^2 -9x +20)^2

This has zeros that can be found by the usual methods of solving quadratics:

x = -3 ±2√14

The positive value of x corresponds to what I might call an "apex." (See the first attachment.) The negative value is where the function turns around an approaches the horizontal asymptote from below. (See the second attachment.)
