Answer:
x should be 55
Step-by-step explanation:
the acute angle is 55 and we know that the whole horizontal is 180 so calculate 180-55 to find the obtuse angle which is 125. Then subtract 70 from that to isolate for x and you get 55.

Answer:
The answer is 2
Step-by-step explanation:
3(2) - 4= 2
6 - 4= 2
2=2
Answer:
60 players should be produced to minimize the marginal cost
Step-by-step explanation:
Following the problem instructions, the marginal cost function is:

Then, to find the x players at
would has its minimum value, we have to find the first derivative as follows:

And the minimum value is determined when:

Then, we solve for x, and these would be the players produced to minimize the marginal cost:

That means at least 60 thousand players must be produced in order to minimize the marginal cost.
D. they never intersect. parallel lines do not cross at any point
