10 Mins till due! :( urgent & will mark :( Jesse and Amir were assigned the same book to read. Jesse started reading on Saturday, and
he is reading 30 pages a day. Amir didn't start until Sunday, but he is reading 35 pages a day.

1. Write an equation to represent the number of pages Amir has read. (Use x for days, y for pages)

2. Using x, the number of days amir has been reading, write an expression to represent the number of day Jesse has been reading.

3. Write the system of equations using answers 1 & 2

4. (Use substitution) Which variable will you substitute for and why?

5. Solve the system of equations.

6. How many days does it take Amir to catch Jesse? At that time how many pages have they read?

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?
