Study Notes
Algebraic Equations
- To evaluate the expression 3x - 7y, substitute x = 5 and y = 2, and simplify.
Quadratic Equations
- To solve the equation 2x^2 - 5x + 2 = 0, use factoring, quadratic formula, or completing the square methods.
Linear Equations
- To find the value of a, solve the system of equations: a + b = 10 and a - b = 4, using substitution or elimination methods.
Time Value of Money
- The formula to calculate the future value of an investment with compound interest is: FV = PV × (1 + r)^n, where FV is future value, PV is present value, r is interest rate, and n is number of years.
- Present value is the current worth of a future cash flow, considering the time value of money.
- Discounting refers to the process of calculating the present value of a future cash flow by adjusting for the time value of money.
