Consider choosing x and y to maximise x7y, while 31ln(3x)+32ln(23y) cannot fall below 1.4. What is the maximised value? (Round to two decimal places.) Your Answer: Answer Select all that is true about the previous question. There is are no valid critical points for the case where the constraint holds with strict inequality because the constraint cannot be satisfied. There is are no valid critical points for the case where the constraint holds with strict inequality because the first order conditions cannot be satisfied. There is are no valid critical points for the case where the constraint holds with strict inequality because the complementary slackness check does not pass. There is are no valid critical points for the case where the constraint holds with strict equality because the constraint cannot be satisfied.
