what is the maximum profit using the vertex (0,60), (16,60), (30,25), (30,0) and the profit function p = 300c + 175?

what is the profit for each vertex? (4 points)
what is the maximum profit? (2 points)

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
