Question

find the value of k if one of the zero of equation 9x^-kx-18 is -1/3

Answer 1

Answer:

The given system of equations: 8x + 5y = 9 8x + 5y - 9 = 0 ….(i) kx + 10y = 15 kx + 10y - 15 = 0 ….(ii) These equations are of the following form: a1x+b1y+c1 = 0, a2x+b2y+c2 = 0 where, a1 = 8, b1= 5, c1 = -9 and a2 = k, b2 = 10, c2 = – 15 In order that the given system has no solution, we must have: Hence, the given system of equations has no solutions when k is equal to find-the-value-of-k-for-which-the-system-of-equations-8x-5y-9-kx-10y-15-has-a-non-zero-solution
