Mr. Kinman is planning to take his study group on a field trip to an amusement park. The regular cost is $18.50 per person. There is a party special that costs $15 per person with an additional $28 fee for a private room where students can eat lunch. Mr. Kinman is trying to decide if he should use the regular price or the party special.

Write an equation in slope-intercept form (y=mx+b) to show the total cost of the regular price with x people, where x = number of students in the study group and y = the total cost.

Aquadratic function f(x) has a turning point at (3,-7). what is the turning point of -f(x)?

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
