The value of a computer is given by the expression 2000+(-2000t),where t is the time in years. Time 1 Year 2 Year 3 Year 4 Year Value B. Describe the change in the value of the computer for each year.
all you have to do for the first part is replace the variable "t" with the year, like for year one 200+(-2000t) you would replace the "t" with a "1" so the expression would be 2000+(-2000*1) so -2000*1=-2000 and -2000+2000=0 so for year one the value would be zero. and so on for the rest of the years for part b you would have to finish the table. then describe the change in value as it says. i hope im right hahah. if im not i apologise .
oh ok . :) do you get it now selena?
