At the performance of Seussical the Musical at your local high school, there are adult tickets and student/child tickets. You’re trying to remember the cost of each to tell your extended family to come see the musical. Your friend, her mom, and her little sister paid a total of $23 on opening night, and you know that another family paid $39 for two adults and three students. If x is cost of adult tickets and y is cost of student tickets, the two equations for these situations can be written as: Convert to slope-intercept form, and use a graphing calculator to graph both equations. (Leave in fraction form, do not round.)

What is the point that is the solution to this system?

This means that adult tickets cost $
and student/child tickets cost $
.

What is the length of an with endpoints a 3,2 and b 8,14

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.
