1 .. Secondar I Chapter 7 Practice Test. The graph of which inequalit would be represented with a dashed line? a. b. c. d. Graph the sstem of linear inequalities. 7 x 7 7 x 7. Graph the solution to this sstem of linear inequalities. Identif solutions to the sstem of inequalities. 7. Which sstem of inequalities is represented b the graph? a. b. c. d. 8. Tell whether the graph of each inequalit would be represented with a dashed line or solid line. a. b. 9. Write an inequalit that is represented b the graph x x + < 7. { x + 7. Which is a solution to the inequalit? a. b. c. d. 7 7 x 7 0. Wa sews small large gloves. It takes her minutes to sew a small pair of gloves 0 minutes to sew a large pair of gloves. The costs of producing the gloves are $ for a small pair $ for a large pair. Wa has hours available to sew gloves. The materials to make the gloves must cost at most $0. The sstem of linear inequalities represents this situation. Explain what the solution (, ) represents for this situation. Be specific!

a. b. c. d.. Marcus has 0 tokens to spend at the school carnival. The Ferris wheel costs 7 tokens the carousel costs tokens.

2 . Write a sstem of linear inequalities that is represented b the graph.. Pablo s pickup truck can carr a maximum of 000 pounds. He is loading his truck with 0-pound bags of cement 80-pound bags of cement. He hopes to load at least 0 bags of cement into his truck. x = =. Which is a solution to the sstem of linear inequalities? a. b. c. d.. Marcus has 0 tokens to spend at the school carnival. The Ferris wheel costs 7 tokens the carousel costs tokens. The inequalit represents the possible was Marcus could use his tokens on the two rides. Graph each inequalit determine if the ordered pair is a solution for the problem situation. Is the ordered pair (, ) a solution for the problem situation? Define the variables write a linear inequalit in two variables to represent each problem situation.. The Foxes are plaing the Titans. The Titans have been scoring 8 or more points per game this season. Between 7-point touchdowns -point field goals, the Foxes need to score more than 8 points to have a hope of winning the game. X = Y = Linear inequalit Define the variables write a sstem of linear inequalities that represents each problem situation.. The maximum capacit for an average passenger elevator is people 000 pounds. It is estimated that adults weigh approximatel 00 pounds children under weigh approximatel 00 pounds. x = = 7. Which of the regions in the graph represent the solution to the sstem. { > x + CIRCLE ONE: A B C D Inequalit Inequalit

0.. The solution (, ) is the point where the sstem of equations intersects. Wa can make pairs of small gloves pairs of large gloves remain at a cost of $0 in hours... D.

6 0.. The solution (, ) is the point where the sstem of equations intersects. Wa can make pairs of small gloves pairs of large gloves remain at a cost of $0 in hours... D.. x = the number of adults = the number of children. x = the number of 0-pound bags = the number of 80-pound bags 7. No. The ordered pair (, ) is not a solution to the inequalit. It is not in the shaded half-plane.
