1) Cinemark movie tickets cost $10 for adult tickets and$8 for child tickets. On a Saturday night the theater sold 645 tickets and made $4525. Which of the following represents this situation? a) x + y = 4525 10x + 8y = 645 b) x + y = 4525 10y + 8x = 645 c) 10x + y =4525 x + 8y = 645 d) x + y = 645 10x + 8y = 4525 2) Using desmos. Graph the following two functions ﻿$f(x)=|x|$﻿ ﻿$g(x)=-6|x|+8$﻿ Correctly select the answer that describes the transformation of g(x) a) x-axis reflection, vertical stretch, shift 8 units down b) x-axis reflection, horizontal stretch, shift 8 units up c) x-axis reflection, vertical stretch, shift 8 units up d) x-axis reflection, horizontal stretch, shift 8 units down 3) Solve the following absolute value inequality ﻿$|5x+10|>25$﻿ 4) Use any method. Which of the following best describes the system below? 3y = - 2x + 5 6x + 9y = 15 a) consistent and dependent (infinite solutions) b) inconsistent (no solutions) c) consistent and independent (one solution) d) inconsistent and dependent (two solutions) 5) The El Paso Plaza sells tickets for their shows for cost of$4 and $6.
