Writing and Graphing Equations in Two Variables Answers

The time spent dancing (minutes) and the amount of calories burned can be modeled by the equation c = 5.5t. Which table of values matches the equation and includes only viable solutions?

The temperature, t, in degrees Fahrenheit, can be found by counting the number of cricket chirps, c, heard in 14 seconds and then adding 40. The equation t = c + 40 models the relationship between the temperature and the number of cricket chirps.What is true about the graph that represents this real-world scenario? Select two options.The graph is continuous.All values of t must be positive.A viable solution is (–2, 38).A viable solution is (0.5, 40.5).A viable solution is (10, 50).

t = 2.5 – 50wt = 50 – 2.5ww = 2.5 – 50t✔ w = 50 – 2.5t

No, time will stop at 30 minutes.✔ No, the tub will be empty by then.Yes, the tub will contain 25 quarts of water.Yes, time continues on forever.

The graph shows the relationship between pounds of grapes, g, and their cost, c.
