Two lines, r and m, are represented by the following equations: line r: 2x 2y = 18 line m: x y = 9 which statement is true about the solution to the set of equations? it is (18, 9). it is (9, 18). there are infinitely many solutions. there is no solution.

Line r is twice line m. i.e. r = 2s which means that they are linearly dependent.

Therefore there are infinitely many solution to the given set of equations.

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
