Select the correct choice below and fill in any answer boxes present in your choice.
 
 
A.
z=
​(Type an integer or a​ fraction.)
 
B.
There is no maximum value of z.
 
At what corner​ point(s) does the maximum value of z​ occur?
 
Select the correct choice below and fill in any answer boxes present in your choice.
 
 
A.
The maximum value of z occurs at the corner​ point(s)
nothing.
​(Type an ordered pair. Use a comma to separate answers as​ needed.)
 
B.
There is no maximum value of z.
Expert Solution
Step 1

To find the maximum value of Z, we have to find the corner points and substitute them in the maximize equation to find the maximum value.
