Ответ:
Possibly
Step-by-step explanation:
It depends on how you're paying it off, is it a set amount or a percentage? If it's by a percentage then the debt never gets completely paid off but I guess that could work. If it's a set amount, such as $50 per month, then it doesn't quite work as what you're paying back relative to the amount of money you still owe changes as time goes on. A better example that I know my math teacher always used was the decay of radioactive material such as Carbon-14 and half-life, all that.
Ответ:
A. (4, 6)
C. (-3, 13)
Step-by-step explanation:
Graphical solutions of two functions are the points of intersection of the graphs of the two functions.
From the graph, the red graph represents a parabolic curve and the blue graph represents a straight line. Both the graphs intersect at two points as shown in the graph.
Therefore, there are two solutions for the given two functions.
The points of intersections as seen on the graph are:
(-3, 13) and (4, 6)
Therefore, the options A and C are correct.
