plss helppp mee! The corporate team-building event will cost $18 if it has 3 attendees. How many attendees can there be, at most, if the budget for the corporate team-building event is $42? Assume the relationship is directly proportional.

15 point ! ~ see if you know the answer to both you!

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
