Answer the following
A total of $20,000 is invested in two corporate bonds that pay 3.5% and 5% simple interest. The investor wants an annual interest income of $790 from the investments. What amount should be invested in the 3.5% bond? $ Find the equilibrium point of the demand and supply equations. Demand Supply p= 530 0.5x p = 298 + 0.3x (x, p) = Solve the system of linear equations and check any solutions aigebraically. (If there is no solution, enter NO SOLUTION. If there are infinitely many solutions, express x, y, and z in terms of the real number a.) x + y + z = 12 2xy + z = 19 - z = 25 (x, y, z) =
