Question

Chapter 3 Review 16154 SJDC Math 090 Instructor: Gallo Solve the problem. S) A customer at a store bought 3 bottles of juice and 8 fruit pies for a total cost of $90.25. Ifx juice and y represents the cost of one fruit pie, write an equation in represents the cost of a bottle of two variables that reflects the given conditions. A) (3x) (8 y)-90.25 B)3x +8y-90.25 D)8x +3y-90.25 C (3 x8 y)-90.25 9) The linear equation in two variables y 2x 40 models the total cost, y, in dollars, for towing a car 9) x miles. The equation indicates that the towing company charges a fixed amount of $40 to send a truck to pick up the car plus a cost of $2 for each mile the car is towed. Find a solution of y- 2x 40 using 2 for x A) (2,4) B) (2, 34) C) (2,44) D) (2, 42) Use the graph to identify the x-and y- intercepts or state that there is no x-or y-intercept. 10) 10) A) x-intercept (1.0y-intercept-(o,-2) B) x-intercept -(1.o y-intercept -(o.2) C)x-intercept-(-2.0 y-intercept (0, D) x-intercept--1.0 y-intercept (0,2) A)x-intercept-(-1,0); y-intercept:0-2) B) x-intercept(i, c)y-intercept (0, 2) C) x-intercept-(1,0 y-intercet(2D) x-interce2y-intercept (o 2)
