10 Select the answer from the menu. The equations y = 7x – 2 and 14x – 2y = 3 represent
(A) parallel lines
(B) perpendicular lines
(C) the same line
(D) intersecting, non-perpendicular lines

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

What is the slope of the line that contains the points (-2,1) and (0,-3)

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?
