Howdy! I have a question on my homework that I do not understand, would anyone be able to help?
Ruth invests $10,000 in two accounts. One account has an annual interest rate of 7% and the other has 5%. Let I represent the total interest earned in one year. Than Ruth's investment can be modelled by the system of equations x+y=10,000 and 0.07x+0.05y=I
Determine the solution for this system of equations that represents the possible investment and find the value of I that corresponds to your solution.
Find the solution for the system if I = 800. Explain why this solution does not represent a possible investment.

If p(x) is the total value of the production when there are x workers in a plant, then the average productivity of the workforce at the plant is a(x) = p(x) x . (a) find a'(x). a'(x) = xp'(x) β p(x) x a'(x) = xp'(x) β p(x) x2 a'(x) = p'(x) β p(x) x a'(x) = xp'(x) β p'(x) x2 a'(x) = p'(x) β xp(x) x2 why does the company want to hire more workers if a'(x) > 0? a'(x) > 0 β a(x) is ; that is, the average productivity as the size of the workforce increases. (b) if p'(x) is greater than the average productivity, which of the following must be true? p'(x) β xp(x) > 0 p'(x) β xp(x) < 0 xp'(x) β p'(x) > 0 xp'(x) β p(x) < 0 xp'(x) β p(x) > 0
