A local zoo has just opened a new stingray environment with 7 young, healthy stingrays. The population of stingrays in the enclosure is expected to at least double every year and can be represented after x years by this inequality. y ? 7(2)? At the time the stingrays were added to the enclosure, the zookeepers determined that the enclosure could sustain at most 160 stingrays. The number of stingrays the enclosure can sustain after x years, because of budget constraints, can be represented by this inequality. y? 160-2x Which point on the graph represents a possible number of stingrays, y, in the enclosure?
