Simplify 2x+6=4x+-2 reorder the terms 6+2x=4x+-2
Answer:
13 1/3 and 6 2/3.
Step-by-step explanation:
Let the 2 parts be x and (20 - x).
So x^2(20 - x) must be a maximum.
y = x^2(20 - x)
y = 20x^2 - x^3
Finding the derivative):
y' = 40x - 3x^2 = 0 for maxm/minm value.
x( 40 - 3x) = 0
40 - 3x = 0
3x = 40
x = 40/3.
This is a maximum because the second derivative y" = 40 - 6x = 40 - 6(40/3)) is negative.
So the 2 numbers are 13 1/3 and 6 2/3.
The answer would be 8 1/4 because if you have the opposite of the opposite you get what you started with. For example the opposite of night is day then the opposite of day is night so you end up with what you started with.
Yes.
They both will end with the equation
.. y = -2x +9
