Question 462756: Can someone please help me!! This is very confusing!!
The value, v, of a shopkeeper's inventory software program is given by v = -1/3t +4, where t is the number of years since the shopkeeper bought the program. What is the program worth 9 years after it is first purchased? Plot the point with the given t-value,9.

You can put this solution on YOUR website!
The value, v, of a shopkeeper's inventory software program is given by
v+=%28-1%2F3%29t%2B4
where t is the number of years since the shopkeeper bought the program. What is the program worth 9 years after it is first purchased? Plot the point with the given t-value,9.
================================================
.
The equation you have given us here tells us the relationship between time and the value of a software program. As the years go by, the program will be worth less and less.
.
Using the equation, the shopkeeper (or you) can calculate the exact value (the variable v) of the software for any number of years (the variable t). Here's how it works:
.
We want to know the value of the software after 9 years have gone by, so we let t=9. Substitute 9 for t in the equation to find the specific v when t=9.
v+=%28-1%2F3%29t%2B4
.
v+=%28-1%2F3%29%289%29%2B4
.
v+=%28-3%29%2B4
.
v=1
.
After 9 years, the software program has a value of 1.

hope this helps!
