1-6. 1-7. 1-8. 1.9. 110. Angelica is working with function machines. She has the two machines shown at right. She wants to put them in order so that the output of the first machine becomes the input of the second. Her initial input is 6. In what order must she put the machines to get a final output of 57 b. Is it possible for her to find an initial input that will get a final output of -57 If so, show how she could do that. If not, explain why not. a. Examine the tile pattern at right. Evaluate each absolute value expression. Review the Math Notes box in this lesson for the definition of absolute value. a. 54 b. -73 c. 13-1-1 a. b. C. d On your paper, sketch Figures 4 and 5. How does the pattern grow? Explain how you know. Simplify each expression. 42+(-17) How many tiles would be in Figure 0 (the figure before Figure 1)? Explain how you know. 8 (-5) b. 8 (-9) C -2(-3X-4) Figure 1 h 5 Figure 2 c. 8(-9) y=x-6 d. 22-5.13 For each equation below, determine the value of y if x-2 A b DU 49 1 18-7 1. Figure 3 11
