Answer:

y-intercept=15 and x-intercept = 5

Step-by-step explanation:

We have the following equation:

3x + y = 15.

To find the x-intercept and y-intercept we have to do the following:

1. To find the y-intercept we need to make x=0, and solve for 'y' as follows:

3x + y = 15 ⇒ 3(0) + y = 15 ⇒ y=15

2. To find the x-intercept we need to make y=0, and solve for 'x' as follows:

3x + y = 15 ⇒ 3x + (0) = 15 ⇒ 3x = 15  ⇒ x=5

Therefore, the y-intercept=15 and x-intercept = 5

Judy is now twice as old as Adam, but 6 years ago, she was 5 times as old as he was. How old is Judy now?
qaws [65]

Answer:

Judy is 16 years old

Step-by-step explanation:

J = Judy's age

A = Adams age

J = 2A

Six years ago   (subtract 6 from the ages)

(J-6) = 5*(A-6)

Distribute

J-6 = 5A - 30

Substitute J = 2A

2A -6 = 5A -30

Subtract 2A from both sides

2A-2A -6 = 5A-2A -30

-6 = 3A -30

Add 30 to each side

-6+30 = 3A-30+30

24 = 3A

Divide by 3

24/3 = 3A/3

8 = A

Adam is 8 years old now

We need to find Judy's age

J = 2A

J = 2*8

J = 16

Judy is 16 years old

Assume that the short-run cost and demand data given in the tables below confront a monopolistic competitor selling a given prod
Damm [24]

Given the information stated above, the firms maximum total profit will be $90. (Option A) See the explanation below.

<h3>What is Maximum Total Profit?</h3>

Maximum total profit is the highest profit

<h3>What is the calculation supporting the above answer?</h3>

It is to be noted that the attached excel spread sheet was computed using the following formulas:

MC(n) = TC(n) - TC(n-1)

MC(n) = marginal cost of nth unit

TC(n) = Total cost of n units of output

MC(1) = 40-25=15 and so on

Recall that

Total Revenue (TR) = Price * Quantity

that is:

TR = P * Q

Marginal Revenue of the nth unit of output  =

TR of the n unit of output - TR of the n-1 units of output.

MR(n)=TR(n)-TR(n-1)

MR(1)=55-0=55 and so on

Recall that Profit = TR  - TC

Thus,

Profit (0) = 0 - 25

= -25 and so on

By observation on the sheet, the maximum profit (that is highest profit attainable) is given as $90.

This corresponds with

  • the Quantity of 4 Unit
  • The Marginal Revenue of 25; and
  • Marginal Cost of 15.

Hence, option A is correct.

Please help!!!!!!!!!!!!
frutty [35]

Answer:

10

Step-by-step explanation:

There is a way to turn this into a simple equation, but I will not go through that.


So the conditions are saying the first term is 40 and for every term after that you multiply the last by .5.  So to get the fifth you would multiply the fourth by .5.


We want the third, so we need to multiply the second by .5.  To get the second we multiply the first by .5.  since the first is 40, 40*.5=20.  Then just repeat.
