Question

Maximize A=xy if 2x+y=16

Answer 1

soooooo

y=16-2x
so put that within the equation

A=x(16-2x)
A=16x-2x^2

taking the derivative of a you get

A'(x)=16-4x
when A'= 0 you get -16=-4x
4=x
if x = 4
y=16-2(4)= 8

x=4
y=8

Answer 2

you can check if you want

if x=1 y =14 A=14
if x=2 y= 12 A=24
...... on and on

Answer 3

hope this helps

Answer 4

=]

Answer 5

but what is the answer or maximum. I was told to maximize it.

Answer 6

I also got x=4 and y=8 but I still don't know what the answer is

Answer 7

how do you get A=24 if x=2??? A= 16-4(2)=2???? no it equals 8, check your math

Answer 8

2(2)+y=16

4+ y = 16
y=12

so if y = 12 wen x =2, you get xy=2*12 = 24

Answer 9

answer to maximum is x=4 y = 8

Answer 10

i'm saying if you aren't sure you can check all the possibles since your number are actually really small it'd be like only 8 or so calculations

Answer 11

so your max will be 32. my math is correct

Answer 12

I also got 32
