    C x = y or no relationship cannot be established between x and y Correct Answer Incorrect Answer
    D x тЙе y Correct Answer Incorrect Answer
    E x тЙд y Correct Answer Incorrect Answer

    Solution

    I. 144x┬▓ - 163x - 65 = 0 144x┬▓ - 208x + 45x - 65 = 0 16x (9x тАУ 13) + 5(9x тАУ 13) = 0 (16x + 5) (9 x тАУ 13) = 0 тИ┤ x = -5/16, 13/9 II. 91y┬▓ - 128y -48 = 0 91y┬▓ + 28y - 156y - 48 = 0 7y (13y + 4) тАУ 12 (13 y + 4) = 0 (13 y + 4) (7y тАУ 12) = 0 тИ┤ y = 12/7, -4/13 Hence, relationship cannot be established between x and y
