Assume a tractor has an initial price of $1000.00 and sells for $100.00 after 23 years. Assume that the tractor’s value depreciates linearly with the passing years.
Let V represent the tractor's value in dollars and let t represent the number of years since the tractor was purchased. Write a formula to express the tractor's value as a function of time: V(t)=

Best ResponseYou've already chosen the best response.0And I know that the vertical intercept of the value function V(t)= 1000 BUT I'm confused on how to get the horizontal intercept

Best ResponseYou've already chosen the best response.2The horizontal intercept is found by plugging in zero for the value of V(t) and solving to find the value of t: 0 = 1000  39.13t ............(1) Now solve equation (1) to find the number of years for the tractor have zero value.

Best ResponseYou've already chosen the best response.20 = 1000  39.13t ............(1) Add 39.13t to both sides. This gives: 39.13t = 1000 Now divide both sides by 39.13, to get the value of t in years. Then round to result.
