What is the value of the function y = 2x + 3 ⁢when x=−1 ?

y = 1

Step-by-step explanation:

In the equation y = 2x + 3, y is defined as  a function of a variable x. As such, the value of y changes as the value of x in a manner defined by the equation.

To get the value of y when x = -1, substitute -1 for x in the equation

y = 2 (-1) + 3

= -2 + 3

= 1

This means that where x = -1, y = 1.

yo answer should be 6 if im not mistaken

step-by-step explanation:

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.
