Answer:
x=o and y= -6
Step-by-step explanation:
12-2x = - 2(y-x)
or,12-2x = -2y + 2x
or, 12 = - 2y + 4x
or, 12/2= 2x - y
or, 2x - y = 6
• 2x -6= y.....eqn_1
-2x=-2y+2x -12
or,4x +2y= -12
or,4x + 2(2x-6)= -12
or, 4x+4x-12=-12
or, 8x= 0
• x= o
putting the value of x in eqn...3
o=(y-0)+6
or, o= y + 6
•y = -6
Answer:
The cost function for
is
.
Step-by-step explanation:
The marginal cost function (
) is the derivative of the cost function (
), then, we should integrate the marginal cost function to find the resulting expression. That is:

Where:
- Fixed costs, measured in US dollars.
If we know that
and
, then:


The cost function for
is
.
