How are the solutions alike? Include a graph in our explanation. Same: both inequalities, both have zero as a solution,both have graphs as solutions, both require division as a final step. Different: Arrow go different directions, circles are different, one answer is whole the other real 5) Write a real-world situation that can be modeled b the inequalit 5f - 75 5. Solve for f and explain how the value of f relates to our situation. Norm is saving five dollars a week for xbox live. He has a $75 off coupon and xbox live is more than $5 per month.

Explain wh it is a function. Then draw a graph that is NOT a function. Explain wh it is NOT a function. Not a function does not pass vertical line test
Is a function does not pass vertical line test 8) Ana was given the following test question to answer. A car travels at a stead rate of 60 miles per hour. Identif the independent and dependent variables. Describe the domain and the range. Write an equation to describe the situation.(pts) Ana wrote the response below The equation is = 60x. The dependent variable is time and the independent variable is distance. The domain and the range are all real numbers. a) If the test item is worth points, how man points would ou given Ana's response? Explain our thinking. No, I would give her two points b) If ou gave Ana less than points for her response, what would ou tell her to add to the response to receive full credit of points. Dependent variable, independent variable, domain and range have errors-see Mrs. Hansen for more details. 9 ) Graph -9x 3 = 6 for the domain D: {,, 0,, }.. = 3x - x (x,) 0 - -
10) The temperature of air in a room that start at 5 o F but increases b 1 0 F ever hour. Write a function that describes the temperature of the air over time. Graph the function to show the temperatures over the first 0 hours. Function:F(x) = 1x + 5 x (x,) Use our graph to predict the temperature at 1 hours. F(1) = 1* 1 + 11 ) Tell whether the set of ordered pairs {( 1,0) (3,-6) (,, -3) (,-8) } satisfies a linear function. Explain wh or wh not.yes 1.) Simplif + 6 - ( - 8) 3 13.) Data was collected on the average winter temperature and the number of das with snow of a random group of cities in the United States. Identif the correlation ou would expect to see between the average winter temperature and the number of das without snow. Positive Correlation 1.) Mrs. Williams is deciding between two field trips for her class. The Science Center charges $50 plus $ per student. The Dino Discover Museum simpl charges $8 per student. For how man students will the Science Center charge less than the Dino Discover Museum? 13 15.) Find the solution for : 6w + 6 10w = -9 w + 13 No Solution 16.) Julia reads books from the librar each month for n months in a row. Write an expression to show how man books Julia read in all. Then, find the number of books Julia read if she read for ears. 58

Let d represent the amount of mone in dollars Alfonso must save to reach his goal. 18.) Solve and graph the inequalit. H 3.7 OR -7 + H < -10.5 19) Solve the inequalit 9 and graph the solution set. 0) The time between a flash of lightning and the sound of its thunder can be used to estimate the distance from a lightning strike. The distance from the strike is the number of seconds between seeing the flash and hearing the thunder divided b 5. Suppose ou are 18 miles from a lightning strike. Write and solve an equation to find how man seconds there would be between the flash and thunder. 1) Simplif ( -) 3. ) Give the domain and range of the relation.

All of the boxes cost the same. Brian is not sure et about the number of boxes of water bottles he wants to bu, but he has enough mone to bu up to 5 of them. Write a function rule to describe how man water bottles Brian can bu. Let x represent the number of boxes of water bottles Brian bus. Find a reasonable range for the function. ) A health club costs $35 to join. Each work out costs $.5. Let w represent the number of workouts. Identif the independent and dependent variables. Then, write a rule in function notation for the situation. Then use the function to calculate f( 6). When will the cost exceed $75.00 for the health club? 5.) Tell whether the function 8 = x - 7 is linear. If so, graph the function. 6.) Sara needs to take a taxi to get to the movies. The taxi charges $1.75 for the first mile, and then $.00 for each mile after that. If the total charge is $1.75, then how far was Sara s taxi ride to the movie?
