Did you know that inequalities can be used to model real-life situations, like a science competition? In this case, a science teacher needs both male and female students for the competition. The number of male volunteers is represented by the variable x, while the number of female volunteers is represented by the variable y. To ensure there are enough students, we use inequalities to describe the situation. The correct inequalities for this scenario are x+y≤15 and x≥6. These inequalities indicate that the total number of volunteers cannot exceed 15, and there must be at least 6 male volunteers. Additionally, x+y<15 and y≥0 are also correct inequalities, as they further describe the situation by stating that the total number of volunteers must be less than 15 and that there must be at least 0 female volunteers.
