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,
.
Answer:
D.
Step-by-step explanation:
Answer:
90%
Step-by-step explanation:
18 divided by 20 = .9 witch means 90% of 1
Answer:
First step is simplifying the equation by moving the square root to the right side and changing it to a Square ²
Step by step:
x-4=7²
(because we changed side square root becomes exponent ²)
x=49+4
x=53
Answer:
4x
Step-by-step explanation:
Like terms are terms that share the same variable (or base) and the same exponents.
5x and x are like terms in that they share the variable x but the coefficients are different.
To combine like terms you would look at the sign (in this case, a subtraction sign) and subtract the two coefficients.
There is an imaginary 1 in attached to x, so you are basically subtracting 1 from 5.
5x - x = 4x
4x is equivalent to 5x - x.
