Marisa drank one cup of milk and ate x small vanilla cookies for a snack. the linear equation below represents y, the total number of calories in marisa's snack.

y= 12x + 120

a. what is the y-intercept represented by this equation?
b. explain what the y-intercept tells us about marisa's snack.
c. what is the slop of the line represented by this equation?
d. explain what is the slope tells us about marisa's snack.
e. if marisa eats 9 small vanilla cookies, what is the total number of calories in her snack? show or explain how you got answer?

Which of the following would be a good name for the function that takes the weight of a box and returns the energy needed to lift it?

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?
