1. Determine whether the lines given by the equations x + y = and =/+
are perpendicular.

2. Two lines having the same -intercept are perpendicular. If the equation of one of
these lines is = −/+, what is the equation of the second line?

3. Given a point (−, ) and a line = x − , what is the slope of the line?

4. Given the point (-3, 6) and a line y=2x-8, write an equation of a line through the point and parallel to the line.

5. Find an equation of a line through (, −) and parallel to the line =/+ .

thank you! will repost if this gets taken down for "too much"

Which of the choices shown could be used to prove that aacp=abcp ?

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 the equation in logarithmic form m^x=n
