WINTER Template Agree... or Disagree?

1.Work with your partner to decide whether you agree or disagree with each answer/solution presented. 2.Write “A” for agree or “D” for disagree on your whiteboard – write it large! 3.Be prepared to explain your choice if called upon. How it works:

Following is the graph for x < #1 Disagree The arrow should point to the left

Following is the graph for x ≥ #2 Agree

#3 A new gaming web site permits young players to play for no more than 30 hours per week. The following inequality represents this situation: x < 30 Disagree There should be a bar under the “less than” symbol to indicate that 30 is a solution.

#4 t -.48 = t = 10 Disagree You need to line up the decimals before adding. The solution is 5.68

Madison is a very picky babysitter. She will not babysit for less than $30 for the entire job. The following inequality represents this situation: b ≥ $30 #5 Agree If the wording is tricky, think about the solutions. Will she babysit for $30? Yes. Will she babysit for $31? Yes. For $29? No.

Dylan has invited 8 friends to his party. His parents say he may invite six more. The following equation and solution represent t, the total number of friends Dylan may invite: t – 8 = 6 t = 14 Dylan may invite14 friends in all #6 Agree

#7 Alexis and Galilee are competing to see who reads the most book pages in a month. Alexis knows that she reads 15 pages a day. She wrote an equation to represent the number of pages she reads in any number of days. She told Galilee: x, the independent variable, is the # of days. Agree

#8 The table below fits this equation: y = 0.75x Disagree When x = 4, y = 3, not 3.5 x1246 y

Sarah bounced a basketball 195 times in three minutes. Her P.E. teacher said this equation would determine how many times Sarah can bounce a basketball in one minute: 3b = 195 #9 Agree

The equation that represents this graph is: #10 Disagree. Correct equation: y = 7x Check y at several values of x. For example when x =2, y = 14 and when x =3, y = 21. y = 9x

#11 If students earned $10/hour washing cars, this graph would be steeper. Agree

#12 In this graph, the number of cars washed is the independent variable and is on the x axis. Agree

We want students to play actively at least 102 minutes each week. This is represented by the following graph: #13 Disagree The circle should be closed to indicate that 102 is a solution of the inequality. 102

CHALLENGE: Andrew runs a mile in six minutes, which is twice as fast as his little brother runs a mile. He says you could use the following equation, where b = his little brother’s pace, to figure out how fast his brother runs: b/2 = 6 #14 Agree. His little brother takes 12 minutes to run a mile.
