Samuel pays $59.99 plus $0.25 for each minute over 450 minutes for his cell phone plan, Monica pays
$64.99 plus $0.10 for each minute over 450 minutes for her cell phone plan. Which system of equations
represents this situation? Let x represent the number of minutes over 450.
A Sy = 59.99x + 0.10
ly= 64.99x +0.25
BS y = 59.99c +0.25
ly = 64.99x + 0.10
( Sy= 59.99 +0.103
1 = 64.99 +0,25
D
S y = 59.99 +0.252
1 = 64,99 +0, 102

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.
