- At the start of the millennium, State A was the third most populous state in the country, followed by State B. Since that time, State B has experienced faster growth. The population y (in millons) of the given state in year x is approximated by the following equations, where x = 0 corresponds to the year 2000, In what year did State B overtake State A in population? To the nearest million, what was the population of these states at that time? State B: 8y - 2x = 160 State A 13y - x = 296 The year State B overtook State A was (Type a whole number.)

Tank 2 initially contains 150 gallons of brine in which 90 pounds of salt are dissolved. At time zero, a brine solution containing 1/2 pound of salt per gallon is added to Tank 1 at the rate of 5 gallons per minute. Tank 1 has an output that discharges brine into Tank 2 at the rate of 5 gallons per minute, and Tank 2 also has an output of 5 gallons per minute. a) Determine the amount of salt in EACH tank at any time t.HINT: Solve for the amount of salt in Tank 1 at time t, and use this solution to help determine the amount of salt in Tank 2.b) Find the time when the concentration of salt in the second tank is a minimum and its corresponding concentration.c) Determine the limiting value for the amount of salt in EACH tank after a very long time.arrow_forwardSolve the following equations: * y" - 3y' + 2y = 2x² + ex + 2xe* + 4e³xarrow_forward
