Ian is working two summer jobs, making $19 per hour lifeguarding and making $9 per hour clearing tables. In a given week, he can work no more than 14 total hours and must earn a minimum of $180. If xx represents the number of hours lifeguarding and yy represents the number of hours clearing tables, write and solve a system of inequalities graphically and determine one possible solution.

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
