hence,
65=5(1-3^n)/1-3
( multiply by -2 on both sides )
130=5(1-3^n)
26=1-3^n
27=3^n
from here, you can use lg to solve for n.
lg 27 = lg 3^n
lg 27 = n lg 3
n = lg 27 ÷ lg 3
hence, n = 3

Answer:
y = .75x - 4.5
Step-by-step explanation:
y = mx + b
m = slope ; b = y-int
slope = rise/ run = 3/4 = .75
y = .75x + b
Because it is hard to determine the exact y-intercept, we plug in a point (2,-3):
-3 = .75(2) + b
-3 = 1.5 + b
-4.5 = b -->
y = .75x - 4.5
