High school math 9th grade i need helps guys Mr. McCoy entered his classroom at 8:00 am and found the temperature to be 86 degrees. He immediately turns on the air conditioner. By 1:00 pm the temperature was down to 76 degrees The temperature went down at an even rate while the air conditioning was running. write an equation to find the temperature in Mr. McCoy's room at any given time between 8:00 am and 1:00 pm

Given abcd ac=38 and ae=3x+4 find the value of x

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?

Which shows the graph of the solution set of 3y – 2x > –18?
