Part A: Explain why the x-coordinates of the points where the graphs of the equations y = –8x and y = –2(x+3) intersect are the solutions of the equation –8x = –2(x+3) . (2 points) Part B: Make a table with 3 columns x, y=–8x, and y=–2(x+3). Make the integer values of x between −3 and 3. What is the solution to –8x = –2(x+3)? ( 6 points) Part C: How can you solve the equation –8x = –2(x+3) graphically? (2 points) (10 points)

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores in recent years has been roughly normal with mean µ = 20.9 and standard deviation s = 4.8. sat scores are reported on a scale from 400 to 1600. sat scores have been roughly normal with mean µ = 1026 and standard deviation s = 209. reports on a student's act or sat usually give the percentile as well as the actual score. the percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. tanya scores 1260 on the sat. what is her percentile (± 1)?
