Dylan works out and burns 10 calories per minute swimming and 7 calories per minute biking. He wants to burn a minimum of 600 calories. Due to daylight limitations, the time Dylan spends swimming must be no less than twice the time he spends biking. Given that x is the number of minutes spent swimming and y is the number of minutes spent biking, determine which inequalities represent the constraints for this situation. x ≤ 2y 10x + 7y ≥ 600 2x < y 7x + 10y > 600 2x ≥ y 7x + 10y ≤ 600 10x + 7y > 600 x ≥ 2y Which combinations of minutes spent swimming and minutes spent biking satisfy this system of inequalities? Select all that apply. (44,25) (46,20) (37,19) (52,12)
