For this case we have the following functions:

The first thing we must do is calculate the sum of functions or equivalently:

We have then:

To complete the sum, we must add the terms whose exponents are equal.
We have then:

Then, we evaluate the function for x = 2:

Rewriting we have:
Answer:
The missing piece belongs in it
Answer:
mary=x
andrew=8
jim=2*8=16
together=4*mary
total=8+16=24
24/4=x
x=6
Step-by-step explanation:
the answer should be about 80 degrees
Answer:
The correct answer is D.
Step-by-step explanation:
Giving the following information:
R = 90x
Total cost= 35x + 17,000
x= is the number of units produced and sold
Now, we know that:
Unitary variable cost= 35
Fixed costs= 17,000
Selling price per unit= 90
To calculate the break-even point in units, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 17,000 / (90 - 35)
Break-even point in units= 309 units
