Question

Solve the following system of equations: {7x - 2y = -9 4x - 5y = -9 x = 7/3, y = 11/3 x = -27/43, y = 99/43 x = -1, y = 1 x = -7/3, y = -11/3 x = -63/43, y = -27/43 _____________ How many solutions does this system of equations have? {-x - 3y = 6 x + 3y = 6 one solution, (0, 0). one solution, (6, 0). One solution, (0, 6), infinitely many solutions. no solution. _________ Simplify. Write your answer using only positive exponents. (3u^3 v/w^-1)^-3 (u^-4 w^-5) = w^2 v^3/9u^13 27 w^9/v^2 9w^9/v^2 w^2v^3/27u^13 w^2/27u^13 v^3 _______ Rewrite without parenthesis and simplify: (x - 7)^2 = x^- 49 x^2 - 14x + 49 x^2 + 49 x^2 + 14x + 49 -49x^2 _________
