Which graph represents the given inequality 2x-5y< -20

The graph of given inequality is shown below

Step-by-step explanation:

The given inequality is

We need to find the graph of this inequality.

The related equation of the given inequality is

Table of values is

 x          y

 0         4

-5         2

-10        0

Plot these ordered pairs on a coordinate plane and connect them by a dotted line.

The related line is a dotted line and shaded region lies above the line because the sign of inequality is <.

The graph of given inequality is shown below.

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2

good luck ! ; )

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.
