Why does the equation 5(3x-4)-6x=3(3x-4) have no solutions? Because when you add -9x to both sides of the equation and simplify, you get -20 = -12

Because when you add -9x to both sides of the equation and simplify, you get -20 = -20

Because when you subtract -9x from both sides of the equation and simplify, you get -20 = -20

Because when you add -9x to both sides of the equation and simplify, you get 0 = -12

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?

Write a description of each inequality. 1. -5a + 3 > 1 2. 27 - 2b < -6 (this < has a _ under it) 3. 1/2 (c + 1) > 5 (this > has a _ under it)
