If fixed costs do not change, then marginal cost also remains constant. equals the change in variable cost divided by the change in output. equals the change in average variable cost divided by the change in output. equals the change in average fixed cost divided by the change in output.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

(23*2)-12=x     x=34

step-by-step explanation:

positive

step-by-step explanation:

the quadrant is facing upwards
