Quinton has an average resting heart rate of 70 beats per minute. When he runs, his heart rate increases by fewer than 50 beats per minute. If b represents his heart rate while running, which statements about the scenario are true? Check all that apply. The inequality b + 50 less-than 70 can be used to represent the situation. The inequality b minus 70 less-than 50 can be used to represent the situation. The graph of the solution set will be shaded to the left. A possible value for b is 120. A possible value for b is 140.
