SHOW WORK Independent Variable “x” ________________________ Equation: ______________________ Dependent Variable _________________________ Answer: ______________ 12. Lindsey sold 4 more shirts than Greg. Fran sold 3 times as many shirts as Lindsey. In total, the three sold 51 shirts. Which represents the number of shirts Greg sold? a. 3g 51 b. 3 g 51 c. 8 5 g 51 d. 16 5 g 51 13. The equation c = 48 +0.06m represents the cost of c, renting a car, and driving m miles. Which statement best describes the cost? a. b. c. d. The cost is the independent variable. The cost is the dependent variable. The cost is constant if the driver drives an even amount of miles. It costs $48 per mile and $6 to rent the car. 14. Determine the equation for the table. x F(x) a. f(x) = 3x-4 2 3 b. f(x) = -2x+7 3 7 5 15 8 27 c. f(x) = 4x-5 d. f(x)= x 3 2 15. Two consecutive numbers plus 3 more totals 10. Which equation would represent the sentence? a. x ( x 2) 3 10 b. x ( x 1) 3 10 c. 2x 3 10 d. 3x 2 10 16. In the equation, 3x 9 7 12 , the first step in solving it should be to….. a. add 3 to both sides b. combine -9 and 7 c. add 9 to both sides d. Divide by -3
