Nina wants to download games for her video game console. older games cost 500points and new releases cost 2000 points. nina has 20,000 points to use. the equation 500a+2000b=20,000, where a is the number of older games and b is the number of new releases, models the situation. how many older games can she download if she downloads one new game? four new games?

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
