Solve the problem.Find the amount in a savings account at the end of 9 years if the amount originally deposited is $1000 and the interest rate is 5.5% compounded monthly.Use: A = P
ntwhere:A = final amountP = $1000 (the initial deposit)r = 5.5% = 0.055 (the annual rate of interest)n = 12 (the number of times interest is compounded each year)t = 9 (the duration of the deposit in years)

Solve the problem.Three solutions of the equation Ax + By + Cz = 20 are given. Use a system of three equations in three variables to find the constants and write the equation.(8, -4, -10), (-8, 4, 20), (3, 8, 11.25)
A. A = 5; B = -5; C = 4; 5x - 5y + 4z = 20 B. A = 5; B = -5; C = 4; 5x + 4y - 5z = 20 C. A = 5; B = 5; C = -4; 5x + 5y - 4z = 20 D. A = 5; B = -5; C = 4; 5x + 4y + 5z = 20
