Answer:

Step-by-step explanation:

this is the equation of a line in slope intercept form with a slope of 1/4 and a y intercept of -5
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.
Let x be the time for the AG800. Then the time for the AG950 is x + 20.


Cross-multiplying and simplifying, we get:

The positive solution to this quadratic is: x = 15.
The answer is: Time for model AG800 = 15 minutes: time for model AG950 = 35 minutes.
