If x can be any number, how many solutions are there for the equation?
y = 3x – 1
a.
there is no solution because there are no values for the variables that make the equation true.
b.
there are two solutions because there are two variables in the equation.
c.
there is only one solution because all equations have one solution.
d.
there are many solutions because there are many values for the variables that make the equation true.

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.
