Answer: x=17
Step-by-step explanation:
7x + 15 = 4x + 66 Subtract 4x from both sides
-4x -4x
3x + 15 = 66 subtract 15 from both sides
-15 -15
3x = 51 Divide both sides by 3
x= 17
As part of a social experiment, Joey sent an email to 2 friends. The email asks the person reading it to forward it to 3 people. The table shows the distribution of the email, assuming that everyone who recelves the email forwards it to 3 new people. Number of iterations Number of People Recelving the Email.
Answer:
I can not see the table, so i will answer this in a general way.
Ok, let's see a rough image of what is happening.
First, Joey sends the email to 2 friends.
So first, 2 people have the email
Then each friend sends the email to 3 new people.
So now the number of people that has the email is:
2 + 2*3 = 2 + 6.
Now, the 6 new people that received the email send it to other 3 new people each, so now the number of people that got the email is:
2 + 6 + 6*3
and so on.
We already can see the pattern here, we can write this as:
∑aₙ
Where aₙ = 3*aₙ₋₁
and a₀ = 2.
So with that information, we can find the number of iterations, n, for a given number of people that received the email A.
A = ∑aₙ = (a₀ + a₁ + a₂ + ....) = (2 + 2*3 + 2*3*3 + ...)

Step-by-step explanation:
A bucket is filled with water up to the 4 gallon mark. The bucket springs a leak and water begins draining at a constant rate of 5/19 gallons per minute. Write a formula to determine the number of gallons of water n in the bucket in terms of the number of minutes t the water has been draining
Answer:
n = 4 - [tex]\frac{5}{19}[/tex]t
Step-by-step explanation:
n determines the amount of water in the bucket, it's basically the total, so that's why it's there. 4 is the number of gallons of water that you started with and 5/19 is the number of gallons that are draining per minute. t is the amount of time or minutes that have gone by. So, that's why the equation is n = 4 -[tex]\frac{5}{19}[/tex]t

Answer: 4 x (8 + 5) = (4 x 8) + (4 x 5)
Step-by-step explanation:
multiply the 4 by what is in the ( )
4x8 = 32
4x5= 20
so it equals what is on the other side (in the blanks, you just plug in the 8 and 5)
so it would be
4 x (8 + 5) = (4 x 8) + (4 x 5)

HELP. LOOK AT THE PICTURE
Answer:
B
Step-by-step explanation:
Since the person used >200 kWh that month, you would use the bottom equation: 0.15(x-200)+20.
(BTW, the x>200 or x≤200 means if they used more or less than/equal to 200 hours)
From there, you can plug in the number of hours for x, which is 400. So, 0.15([400]-200)+20
0.15(200)+20
30+20
50
The bill for a person that uses 400 KWh is $50.
Option B is the correct answer.
We have,
The number of kilowatts is more than 200.
So,
From the piecewise function choose the function for x > 200.
i.e
b(x) = 0.15 (x - 200) + 20
This is used to calculate the bill.
Now,
Substitute x = 400 KWh in b(x).
b(x) = 0.15 (x - 200) + 20
Simplify the expression.
= 0.15 (400 - 200) + 20
= 0.15 x 200 + 20
= 30 + 20
Add the values.
= 50
Thus,
The bill for a person that uses 400 KWh is $50.

Carlos is building a game room adjacent to his living room so that both rooms will have the same width. he created the model shown below. (x+4) (2x+6) (x-4)Part A: write an expression for the total area of both rooms Part B: if the length of the game room is 12 feet, what is the total square footage of the two rooms??
Answer:
1,000 sq ft
Step-by-step explanation:
Part A:
To find the total area of both rooms (length x width):
(x+4)(2x+6+x-4)
(x+4)(2x+2+x)
2x²+2x+x²+8x+8+4x
= 3x²+14x+8
Part B:
If the length of the game room = 12 ft, we can solve for x:
Game room = (x-4)=12; therefore x=16
Plug 16 in for x in the equation from Part A:
3x²+14x+8 becomes 3(16)²+14(16)+8
= 1,000 sq ft

fill this storage unit?
6 ft
7+ A
44 ft
Answer:
the number of boxes that would take fill
the storage completely is 60 boxes.
Step-by-step explanation:
given:
A storage unit has the dimensions 6 ft. x 7 1/2 ft. x 4 1/2 ft.
find:
What number of
1 1/2 ft. x 1 1/2 ft. x 1 1/2 ft. cardboard boxes would it take to completely
fill this storage unit?
Volume of a storage unit = 6 x 7.5 x 4.5
Volume of a storage unit = 202.5 ft³
Volume of a cardboard box = 1.5 x 1.5 x 1.5
Volume of a cardboard box = 3.38 ft³
to get the number of cardboard boxes to fill in the storage unit,
Number of boxes = 202.5 ft³
3.38 ft³
Number of boxes = 60
therefore,
the number of boxes that would take fill the storage completely is 60 boxes.

A store sells bouquets of fruits for $10 a bouquet. The daily cost to produce x bouquets of fruits is defined by the function f(x) = – x 4 + 3x 3 + 5x 2 + 20x + 1.
Answer:
5 or C
Step-by-step explanation:
when you plug in 5, you get -24 as the cost. Then you take that number with the amount of money you make selling 5 flowers and that would be $50 since they are $10/per bouquet. Then when you subtract you get a positive profit of $26.
Answer:
5
Step-by-step explanation:
For profit to be had, the selling price (represented by $10x, x being number of bouquets sold) must be greater than the cost to produce (here, -x^4 + 3x^3 + 5x^2 + 20x +1).
Set up an inequality such that 10x is greater than the cost to produce.
10x > -x^4 + 3x^3 + 5x^2 + 20x + 1
-Solving the inequality by subtracting 10x from both sides, we have:
0 > -x^4 + 3x^3 + 5x^2 + 10x + 1
-Using a graphing calculator, (the one they give you on Edgenuity) graph the new function and look for where the graph is below the x axis. (y is less than 0)
Looking at the graph, we see that when x is greater than 0, (you can't sell a negative amount of bouquets) y is greater than 0 up until x = 4.579. After 4.579, the y values become negative. (what we want to be looking at according to the inequality.)
You can't sell 4.579 bouquets, and even if you could, you'd be breaking even, with y=0. The answer isn't 4, because according to the graph and inequality, y would be greater than 0 (making the inequality false). Because of this, we have to find the next whole positive number that would make the inequality true, and that is 5.
