Am not sure but maybe no because i learned it 2 month ago
Answer:
Step-by-step explanation:
Given is a function f in two variables as
To find critical points of the given function and also to find max, min or saddle point.
Find the partial derivatives
Equate first derivatives to 0
Adding fx and fy we get
x=±y
Only real roots are (x,y) =(3,3) and (-3,-3)
(3,3) is a saddle point
(-3,-3) is also a saddle point.

Required
Determine the discount
The discount is calculated by multiplying the price off by the original price:
Convert % to decimal
<em>Hence, the amount of discount is $19.98</em>
Answer:
125
Step-by-step explanation:
5^3=5*5*5
5*5=25
25*5=125
Answer:
x - 4y = 8
Step-by-step explanation:
Since the Point-Slope Formula is already given to you, convert it to Slope-Intercept Form, and you do that by doing this:
y - 1 = ¼(x - 12) >> y - 1 = ¼x - 3
y - 1 = ¼x - 3
+ 1 + 1
--------------
y = ¼x - 2 >> Slope-Intercept Form
After doing this, you are ready to convert to Standard Form, and you do that by doing this:
y = ¼x - 2
-¼x -¼x
-----------
-¼x + y = -2
Now unfortunately, we do not want fractions as our coefficients, so the way to eliminate the fraction is to multiply the equation by the Multiplicative Inverse of -¼, which is -4:
-4[-¼x + y = -2] >> x - 4y = 8 → New equation without fractions
