On the basis of past experience a company has determined that its monthly sales revenue (in dollars) is related to its advertising according to the formula s = 20x + y2 + 4xy, where x is the amount spent on print advertising and y is the amount spent on cable advertising. If the company plans to spend $34,000 on these two means of advertising, how much should it spend on each method to maximize its monthly sales revenue?

What is the solution of the systems of equations? y=2/3x+3 x=-2

The management of a supermarket wants to adopt a new promotional policy of giving a free gift to every customer who spends more than a certain amount per visit at this supermarket. the expectation of the management is that after this promotional policy is advertised, the expenditures for all customers at this supermarket will be normally distributed with a mean of $95 and a standard deviation of $20. if the management wants to give free gifts to at most 10% of the customers, what should the amount be above which a customer would receive a free gift?

Order the equations from least to greatest based on the number of solutions to each equation.-4^x -1 = 3^(-x) – 2 -3x + 6 = 2^x+13^x – 3 = 2x - 2
