You are multiplying 2 to each term each time.
-40 is the 4th term
-40 x 2 = -80
-80 x 2 = - 160
-160 x 2 = -320
-320 x 2 = -640
-640 x 2 = -1280
-1280 x 2 = -2560
-2560 x 2 = -5120
-------------------------------------------------------------------------------------------------------------------
-5120 is your 11th term.

As the independant variable increases, the dependant variable increases at a constant rate creating a linear relationship.
Can't see the table but direct variation is: y = kx
So if the output is some constant multiple which could be positive, negative or fraction then yes it is direct variation. So just divide a couple y/x = k to see what you get.
Answer:
The domain is t ≥ 0
The range is D ≥ 0
Step-by-step explanation:
D(t) = 100t + d₀
t is the time measured in hours.
d₀ is the initial position of the train.
We can assume the distance they go is not negative so...
The domain is t ≥ 0
The range is D ≥ 0
The total cost of the tent is 409.86

explanation:
230×0.65=149.50
230+149.50=379.50×.08=30.36
379.50+30.36=409.86
(Hope this helps :) )
