Your sequence
-8, 16/3, -32/9, 64/27
is a geometric sequence with first term -8 and common ratio
(16/3)/(-8) = (-32/9)/(16/3) = -2/3
The general term an of a geometric sequence with first term a1 and ratio r is given by
an = a1·r^(n-1)
For your sequence, this is
an = -8·(-2/3)^(n-1)
Answer:
C y = 1/5x - 1
Step-by-step explanation:
Slope intercept form: y = mx + b where m = slope and b = y-intercept.
Substitute into the slope intercept form m= 1/5 and b = -1
y = 1/5x - 1

Answer:
day 2) 100
day 3) 140
day 4) 180
day 5) 220
day 7) 300
Step-by-step explanation:
the equation would be y= 40x + 20 since 20 is the starting price and everyday you add 40 dollars. put in what day it is as X to get the answer
