For a geometric sequence or geometric series, the common ratio is the ratio of a term to the previous term. This ratio is usually indicated by the variable r. Example: The geometric series 3, 6, 12, 24, 48, . . . has common ratio r = 2.
Answer:
Option C
Therefore, one of the factors of 
is 
.
Step-by-step explanation:
Given:
the common factor from 
and 
is 4.
therefore, 
Now, use the formula for above expression: 
here, 
and 
Therefore, we have
Therefore, one of the factors of is .
3 1/2 pound = 7/2 pounds.
We know that the dog eats 7/2 (3.5) pounds every 21 days since there are 7 days in a week and Mr.Z only buys dog food every 3 weeks.
Set up a proportion. <u>3.5 lb</u> = <u> x </u><u>
</u> 21 days 365 days
<u>
</u>Cross multiply and divide. 3.5 lb x 365 days = 1277.5 / 21 days = 60.83 lb

The y intercepts are 9 and -9 because the y coordinate is zero so they would be plotted ob the y axis and 7 is an x intercept because the x coordinate in the ordered pair is zero.
