PLEASE HELP!!! 40 points!!!1) A school puts on a play. The play costs $1,200.00 in expenses. The students charge $4.00 for tickets. There will be 1 performance of the play in an audiotorium that seats 500 people. What is the domain of the function that shows the profit as a function of the number of tickets sold?A)The domain is all real numbers from negative 1,200 to positive 2,000.
B) The domain is all integers from negative 1,200 to positive 2,00.
C) The domain is all integers from 0 to 500.
D) The domain is all real numbers from 0 to 500.
2) A student is running a 3-kilometer race. He runs 1 kilometer every 2 minutes. Select the function that describes his distance from the finish line after x minutes.
A) f(x)= -1/3x+2
B) f(x)= -1/2x+3
C) f(x)= 1/2x+3
D) f(x)= 1/3x+2
3) A coal car on a train weighs 30 tons plus 1 ton per cubic yard of coal x that it carries. The total weight of a coal car is f(x)= x+30. How will the graph of this function change if the coal car weight is changed to 26 tons?
A) The line will shift vertically up by 4 tons.
B) The line will shift vertically up 26 tons.
C) The line will shift vertically down by 4 tons.
D) The line will shift vertically down by 26 tons.
Answers
#2, He runs 1 kilometer every 2 minutes. That means he will run 1/2 kilometer per minute. Your answer is C.
#3, the equation would change to f(x) + 26
So it would shift vertically down by 4 tons. Your answer is C.

I'm not exactly sure what your exact question was so i just answered the document in the question. It's simple math really. I'm an AP Math student. Then again, I could still be wrong since I do not know what it is you're learning.

For this case we have that the main function is given by:
We apply the following transformation:
Vertical displacements:
Assume k> 0
To graph y = f (x) - k, move the graph k units down.
For k = 3 we have:
Answer:
when the function is changed to f (x) - 3 the change that will occur is:
Vertical displacement 3 units down.

3 g fiber *2= 6 g fiber.
There is 6 g fiber in 1 cup of oatmeal. Therefore, the number of fiber in 1 1/8 (which is 1 1/8 times as large as 1) cups of oatmeal is:
6 g fiber *(1 1/8)= 6.75 g fiber.
There is 6.75 g of fiber left in the box.
Hope this would help~
3 grams of fiber x fiber
______________=_________
1/2 cup 1 1/8 cup
Cross multiply
1/2x=3 3/8
divide both sides by 1/2
x=6.75 or 6 3/4
There is 6 3/4 grams of fiber in 1 1/8 cups of oatmeal.

Thats the first option. It came out Positive! :)

Thats the second option, it came out negative.

=0
Thats the fouth option, it came out as Positive zero.
