Sum of a finite geometric series=a(r^(n) -1)/(r -1)
or
sum of a finite geometric series=a(1 - r^(n))/(1 - r)

Answer:
8/5
Step-by-step explanation:
We can use the formula for finding slope for this: 
The answer would be 8/5
Answer:
a) 105 degrees
b) 75
c) 105
Step-by-step explanation:
a) 180-75 is 105 (supplementary angles)
b) same angle as kings ave and 4th street. (supplementary angles)
c) 180-75 is 105 (also vertical angle rule)
3y - 1 = 28
+ 1 + 1
----------------
3y = 29
---- ----
3 3
y= 9.66
Using the slope formula the answer would be 1-(-1)/(-1)-6. The slope would be 2/-7. It would be a negative slope.
