50 - 3n = 7n + 80
    +3n     +3n ( add 3n to both sides)
50 = 10n + 80
-80            -80 (subtract 80 from both sides)
-30 = 10n (divide both sides by 10)
n = -3

Beth purchased a computer, and its value depreciated exponentially each year. Beth will sketch a graph of the situation, where x
Katyanochek1 [597]

What is x?

It is the number of years since purchase. Can this be negative?

NO! Years cannot be negative. So we disregard negative x-axis.


What is y?

It is the value of the computer at that year. A computer starts off with a positive value (y axis) and depreciates to 0 after some years. Can this be negative?

NO! At 0 value, the computer is worth nothing! There is nothing known as <em>negative </em>value. So we disregard negative y-axis.


The graph that Beth will sketch will have to be in the 1st quadrant (positive x-axis & positive y-axis).

ANSWER: Quadrant I only

Mr. Webb gave his waiter a $8.60 tip on a $50 bill. What percent did he give the waiter?
Dominik [7]
<u>8.60</u> =  <u>  X  </u>
 50       100

"Percent" means "out of one hundred" (Latin).
Multiply the top by two, since 100 is twice 50, and the fractions will be equal.
The answer is 17.2%.
