Answer:
are the values of a or b given?
Step-by-step explanation:
A = 30,000 - 2000m where A=altitude and m = number of minutes
After 5 minutes A ( altitude) = 30,000 - 2000(5) = 20,000 feet
Using a graphical tool we obtain that the solution of this system
(intersection between the lines)
is given by the point
(x,y) = (2,4)
