Answer:
y=2
Step-by-step explanation:
x+y=8
6+y=8
6+2=8
so y=2
Let's multiply each of the four squares, one by one.
In blue, we see the dimensions are x by x. x times x = x^2
In pink, we see the dimensions are 9 by x. x times 9 = 9x
In green, the dimensions are x by 3. 3 times x = 3x
And finally, yellow's dimensions are 3 by 9. 3 times 9 = 27
We can now just add all these areas to find the total area:
x^2 + 12x + 27
Answer:
- Peter is a compulsive gamer. He decides to buy World of Warcraft, all of its expansions, Starcraft 2, a PS3, a Wii, and an Xbox 360 since prices in general have been rising at an alarming rate. <u>INFLATION
</u>
- <u>
</u>Melissa decides to start her own personal library and chooses to amass a private collection of books and magazines about world religions, cooking, comics, and economics. As she reads an issue of The Economist, she discovers overall price levels have changed only 0.01% in the past 2 years and decides it doesn't matter whether she starts the project now or later. <u>PRICE STABILITY</u>
- Linda postpones her wedding even though most food prices and most service prices were dropping this year, which would help keep the cost of the wedding down. <u>DEFLATION</u>
<u>Linda's</u> money earned the most value because deflation means that the currency is gaining value as time passes. It is the opposite to inflation where a currency loses value as time passes.
For this case we have a function of the form:
y = A (b) ^ t
Where,
A: initial amount
b: growth rate
t: time
Substituting values we have:
V (t) = 2000 (1.02) ^ t
Answer:
a function that gives the total value V (t) in dollars, of the investment t years from now is:
V (t) = 2000 (1.02) ^ t
You just take the original slope and do opposite, reciprocal
Ex:
slope= 2/3
perpendicular slope= -3/2
