(a+b+c)^3 formula Let p denote this unknown number and v 0 the initial principal. The total debt by the end of the first month is: v 1 = R v 0 − p, because the principal yields interest but p is paid off. Similarly, v 2 = R v 1 − p = R ( R v 0 − p) − p = R 2 v 0 − R p − p. By induction, it is not difficult to see that.

ln (x + 4) + ln (x - 2) = ln 7. First we use property 1 of logarithms to combine the terms on the left. ln (x + 4)(x - 2) = ln 7. Now apply the exponential function to both sides. e ln (x + 4)(x - 2) = e ln 7. The logarithmic identity 2 allows us to simplify both sides. (x + 4)(x - 2) = 7. x 2 + 2x - 8 = 7. x 2 + 2x - 15 = 0 (x - 3)(x + 5) = 0. x = 3 or x = -5 For instance, make sure that a summation begins with i=1 before using the above formulas.

Jun 04, 2019 · x = 2. To find the value of y, substitute 2 for x in the first equation. y = –3(2) + 4 = –6 + 4 = –2. Therefore, the solution of the given system of equations is x = 2,y = –2. Check this solution by substituting the values into the second equation and making sure the resulting equality is true. 2. A.
