Answer:
Step-by-step explanation:
use these two equations
A: y = 15
B: y = 2r + 5
a) set the equations equal to eachother for your first answer
15 = 2r + 5
B) solve for r
15 = 2r + 5
10 = 2r
5 = r
after 5 rides the cost will be the same
Answer:
a(9) = 150*(0.4)^8 = 0.098304
Step-by-step explanation:
This is a geometric sequence, because each new term is 0.4 times the previous term.
The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1). Here, with a(1) = 150 and r = 0.4, we have:
a(n) = 150*(0.4)^(n - 1), and so
a(9) = 150*(0.4)^8 = 0.098304
Answer: yes that is a function
Step-by-step explanation:
It is a function because every y value has a unique x value
