Step-by-step explanation:

<u>Step 1:  Use two points</u>

<u />(x_1,y_1) → (-3, 5)

(x_2,y_2) → (-2, 2)

<u>Step 2:  Find the slope</u>

<u />m = \frac{y_2-y_1}{x_2-x_1}

m = \frac{2 - 5}{-2 - (-3)}

m = \frac{-3}{-2+3}

m = \frac{-3}{1}

m=-3

A. 2, 200, 2000  

This is multiplying the number by 10 each time. In other words, just adding an extra zero to the end of it. 

b. 340, 0.034 

This one is moving the decimal place forward two places. 10^-2, so removing two zeros from the end of it until eventually you reach decimals and have to move the decimal forward twice, which is essentially what you're doing here.

c. 85700, 857, 0.857

In this one, you remove one zero from the end. You move the decimal forward once when you reach the decimals. This would be 10^-1

d. 444000, 4440000, 44400000

In this one, you multiply each one by 10. Add on a zero to each one.

e. 0.095, 9500000, 950000000

You multiply this one by 10^2, so the number increases.

Hotel Management: The Airgle AG800 can purify the air in a conference hall in 20 fewer minutes than it takes the Airgle AG950 to
marta [7]
Let x be the time for the AG800. Then the time for the AG950 is x + 20.
\frac{1}{x}+\frac{1}{x+20}=\frac{2}{21}
\frac{x+20+x}{x(x+20)}=\frac{2}{21}
Cross-multiplying and simplifying, we get:
2x^{2}-2x-420=0
The positive solution to this quadratic is: x = 15.
The answer is: Time for model AG800 = 15 minutes: time for model AG950 = 35 minutes.
