(1,3) is the answer if this is question because you haven't given graph.
In order to figure this out you need to use Descartes Rule. I attached a picture showing Descartes Rule. If the signs changes for when x is positive then the number of times it changes are the possible positive solution. If the sign changes when x is negative then the number of times it changes are the possible negative solutions. With that said the answer is A. View the picture I have attached for the possible + - and imaginary solutions.
Answer = A) One possible positive solution.
Answer = A) One possible positive solution.
They will have same amount in 45 weeks.
Step-by-step explanation:
Given,
Starting amount of Nancy = $425
Per week saving = $25
Let,
x represent the number of weeks.
N(x) = 25x+425
Starting amount of Seamus = $875
Per week saving = $15
S(x) = 15x+875
For same amount;
N(x) = S(x)
Dividing both sides by 10
They will have same amount in 45 weeks.
