Solve the problem using your calculator. 6) The paired data below consist of the temperatures on randomly chosen days and the amount a 6) certain kind of plant grew (in millimeters). Use a graphing calculator to model the data with a linear function that predicts a plant's growth as a function of temperature. Temp 62 76 50 51 71 46 51 44 79 Growth 36 39 50 13 33 33 17 6 16 A) y = 7.30 + 0.122x B) y = - 14.6 - 0.211x C) y = 14.6 + 0.211x D) y = 7.30 - 0.112x Solve the equation. 7) 7x + 6 = 3x - 18 7) A) - 6 B) - 9 2 C) - 24 D) 6 Solve the problem. 8) To convert a temperature from degrees Celsius to degrees Fahrenheit, you multiply the 8) temperature in degrees Celsius by 1.8 and then add 32 to the result. Express F as a linear function of c. A) F(c) = c - 32 1.8 B) F(c) = 33.8c C) F(c) = 1.8c + 32 D) F(c) = 1.8 + 32c Find the slope of the line containing the given points. 9) (- 4, 6), (- 2, 6) 9) A) 2 B) not defined C) - 2 D) 0 Find the center and radius of the circle. 10) x 2 + y 2 = 4 10) A) (0, 0); 4 B) (0, 2); 4 C) (2, 2); 4 D) (0, 0); 2
