Answer:
Option C - 420
Step-by-step explanation:
Given : Objective function, P, with the given constraints

Constraints,


To find : What is the maximum value
Solution :
First we plot the graph through the given constrains.
As they all move towards the origin the common region of the equations is given by the points (0,0), (0,12), (2,10), (4,0)
Refer the attached figure.
So, we put all the points in P to, get maximum value.






Therefore, The value is maximum 420 at (0,12)
So, Option C is correct.
Answer:
19 shows direct variation
20 does not (guessing for this one a bit)
19- Shows a steady increase of four in y for each one in x
20- Shows no increase
Step-by-step explanation:
19 is a constant increase by 4, 20 does not show either
The area would be 128ft^2 because 2^4 is 2x2x2x2 and 2^3 is 2x2x2 and if you multiply them you get 128ft6=^2
Floor seats because for every balcony seat you get 20 floor seats.
hope this helps :P
X + 3 = 9-4
First simplify the right side.
9-4 = 5
Now you have x + 3 = 5
Now subtract 3 from both sides:
X = 2
Answer: x = 2
