-36×+9 is equivalent to this question.
Answer:
Step-by-step explanation:
207
2 thousands+ 2 tens = 2070
divide that by 10
2070÷10= 207
Point form: (1,-1)
equation form: x = 1, y = -1
The Lagrangian is

It has critical points where the first order derivatives vanish:



From the first two equations we get

Then

At these critical points, we have
(maximum)
(minimum)
