A. In Problem 3, the equation of the line of best fit y = 409.43x – 815,446.71 gave the cost y of attending a four-yeal public college in academic year x. You used
x = 2000 to represent academic year 2000-2001. Estimate the cost of attending
a four-year public college in the 2016-2017 academic year.

Place the following steps in order to complete the square and solve the quadratic equation,

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =

The cost varies directly with the number of tickets purchased. it costs $145 for 10 people to attend a concert. a. what is the constant of proportionality (k)? b. write the direct variation equation. c. home much does it cost for 8 people? d. graph this situation. be sure to label each axis and give the graph a title.
