Answer:
c+2
Step-by-step explanation:
Distribute the Negative Sign:
=9c2+3c+9+−1(9c2+2c+7)
=9c2+3c+9+−1(9c2)+−1(2c)+(−1)(7)
=9c2+3c+9+−9c2+−2c+−7
Combine Like Terms:
=9c2+3c+9+−9c2+−2c+−7
=(9c2+−9c2)+(3c+−2c)+(9+−7)
Answer:
c + 2
Step-by-step explanation:
(9c² + 3c + 9) - (9c² + 2c + 7)
9c² + 3c + 9 - 9c² - 2c - 7
9c² + 3c + 9 - 9c² - 2c - 7

Amber and Will are in line together to buy tickets. Amber moves back by 3 places three times to talk to friends. She then is invited to move 5 places up in line. Will moved back by 4 places twice, and then moved up in line by 3 places. Overall, who moved farther back in line?
Answer:
Amber
Step-by-step explanation:
Lets pretend they both started at 10
Amber moved back 3 places 3 times, (1), then moved up 5 places (6)
Will moved back 4 spaces twice (2) then moved up 3 places (5)
6 > 5, therefore the answer is Amber

Answer: The square root of π has attracted attention for almost as long as π itself. When you’re an ancient Greek mathematician studying circles and squares and playing with straightedges and compasses, it’s natural to try to find a circle and a square that have the same area. If you start with the circle and try to find the square, that’s called squaring the circle. If your circle has radius r=1, then its area is πr2 = π, so a square with side-length s has the same area as your circle if s2 = π, that is, if s = sqrt(π). It’s well-known that squaring the circle is impossible in the sense that, if you use the classic Greek tools in the classic Greek manner, you can’t construct a square whose side-length is sqrt(π) (even though you can approximate it as closely as you like); see David Richeson’s new book listed in the References for lots more details about this. But what’s less well-known is that there are (at least!) two other places in mathematics where the square root of π crops up: an infinite product that on its surface makes no sense, and a calculus problem that you can use a surface to solve.

you are watching a game of poker on ESPN with your friends. You are trying to figure out the value of each colored chip that is being played. Supposed 12 white, 9 red, 8 yellow, 4 blue, and 0 green chips can be exchanged for 2 white, 1 red, 0 yellow, 1 blue and 1 green chip. Also. supposed 1 green= N blue, 1 blue= N yellow, 1 yellow= N red, and 1 red= N white.
what is the whole number rate of exchange for these chips?
is only one exchange rate possible?
9514 1404 393
Answer:
N = 5; only one rate is possible
Step-by-step explanation:
The values of the sets of chips are ...
12 +9N +8N^2 +4N^3
and
2 +N +N^3 +N^4
We want to find N such that the difference in value is zero:
N^4 -3N^3 -8N^2 -8N -10 = 0
A graphing calculator can show us the roots. There is only one positive real root to this equation: N = 5.
The exchange rate N is 5. Only one rate is possible.

Which of the following is a cause of inflation?
consumers growing apathetic and failing to notice attempts to raise prices
b demand continually exceeding supply, leading to an imbalance of money and goods in the
market
C a natural consequence of the use of money instead of trade goods
d government intervention demanding that prices be raised
Answer:
D. government intervention demanding that prices be raised

The answer choice which is a cause of inflation is; Choice B; demand continually exceeding supply, leading to an imbalance of money and goods in the market.
What is then cause of Inflation?Inflation is simply a measure of the rate of rising prices of goods and services in an economy. More specifically, a surge in demand for products and services can cause inflation as consumers are willing to pay more for such product in less supply.

At summer camp, there are 3 boys for every 4 girls. If there are 63 boys & girls at camp, how many boys are there?
Answer:
turn it into an equation
since the total number of students is 63 and for every 3 boys are 4 girls
3x + 4x = 63
7x = 63
x = 63/7
x= 9
to get the number of boys
3 x 9 = 27
therefore the number of boys is 27

In order to finance furniture for an office in a new retail store, Tools for Schools signs a 140-day simple discount note with a maturity value of $19300. Find the proceeds if the discount rate is 13.5%.
Answer:
I think it would be $ 66.23
I hope I can help you
have a nice day.
The proceeds of the simple discount note are approximately $18,296.16.
To find the proceeds of the simple discount note, we can use the formula:
Proceeds = Maturity Value - Discount
Where:
Maturity Value = $19,300 (given)
Discount = Maturity Value * Discount Rate * Time
The discount rate is 13.5%, which can be written as 0.135 in decimal form. The time is 140 days. Now, let's calculate the discount:
Discount = $19,300 * 0.135 * (140/360)
we divide by 360 because simple interest is typically based on a 360-day year.
Discount = $19,300 * 0.135 * 0.388888...
Discount ≈ $1,003.84 (rounded to two decimal places)
Now, let's find the proceeds:
Proceeds = $19,300 - $1,003.84
Proceeds ≈ $18,296.16 (rounded to two decimal places).

A recipe for making paste calls for a ratio of flour to water of 4:2. If you only have 2 cups of flour, how much water should you put in? Explain how you know.
Answer:
1 Cup of Water
Step-by-step explanation:
Well, this is pretty simple.
This questions topic is known as Equivalent Ratios.
To find an equivalent ratio, add or divide the numbers by the same amount.
Let's do it together.
4:2 is the ratio we already have. If we have to make it have 2 cups of flour, let's divide 2 on both sides.
Since 4 divided by 2 is 2, and 2 divided by 2 is 1,
We can confirm that you would need to put in 1 cup of water.

What is an equation of the line that passes through the point (4,-6) and has a slope of -3 solve problem
Answer:
y = -3x + 6
Step-by-step explanation:
1. the equation has a slope of -3 => y = -3x + b (b is the number we'll find now)
2. From the point (4,-6) => x = 4, y = -6
=> -6 = (-3)(4) +b
=> b = 6
Anyone know how to do this?
Answer:
y=3/2x+2
Step-by-step explanation:
3/2 is the slope of the line and 2 is the y-intercept which is where the line crosses the y-axis. The slope is the rise over run or the rate of change of the y-value over the x-value.
