1. graph each system of inequalities. then use your graph to identify a solution to the system x - y less than or equal to 7 and x + 2y < 5 a. (6,1) b (8,-1) c (6,2) d (6,-2) graph each system of inequalities. then use your graph to identify a solution to the system 2x+4y> 0 and -x+5y> 0 a (0,0) b (-4,-2) c (6,2) d (6,0)

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.

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!
