Answer:
-13 yards
Step-by-step explanation:
Estimating that we start off on the middle line, we could solve this by simply looking at a number line. Moving 9 yards ahead would put us at 9. But moving back 22 would place us at a negative number. An easy way of doing this is subtracting 9 from 22:
22 - 9 = 13
But, we already know that since the answer is to the left of zero, it will be a negative number. So we flip the sign to get -13 yards.

Answer:
The series converges to
for
Step-by-step explanation:
Given the series is 
We have to find the values of x for which the series converges.
We know,
converges to (a) / (1-r) if r < 1
Otherwise the series will diverge.
Here,
is a geometric series with |r| = | 9x |
And it converges for |9x| < 1
Hence, the given series gets converge for 
And geometric series converges to 
Here, a = 1 and r = 9x
Therefore, 
Hence, the given series converges to
for
