Below = a negative number (-)
-2
up = positive number
5
the equation would be -2+5 = ?
and the answer/ integer that represents the new location is 3

krek1111 [17]

Answer:

The answer to your question is below

Step-by-step explanation:

a) Find to points of the line and find the equation of the line.

A ( 0, -4)            B (2, 0)

slope = m = \frac{0 + 4}{2 - 0}

     m = \frac{4}{2}

            m = 2

Line equation

                      (y - y1) = m (x - x1)

                      (y - 0) = 2(x - 2)

                            y = 2x - 4

Write the line as an inequality

                           y ≥ 2x - 4

b) Yes, (2,0) is a solution of the inequality

                           y ≥ 2x - 4

                           0 ≥ 2(2) -4

                           0 ≥ 4 - 4

                           0 ≥ 0              This is true

c) No, (4, -2) is not a solution.

                          y ≥ 2x - 4

                         -2 ≥ 2(4) - 4

                         -2 ≥ 8 - 4

                         -2 ≥ 4               This is false

Using it's concept, the approximate perimeter of pentagon ABCDE is given as follows:

34.4 units.

<h3>What is the perimeter of a figure?</h3>

The perimeter of a figure is given by the sum of the lengths of it's outside dimensions.

In this problem, the vertices are in a coordinate-plane, hence the distances are found using the formula for the distance between two points.

<h3>What is the distance between two points?</h3>

Suppose that we have two points, (x_1,y_1) and (x_2,y_2). The distance between them is given by:

D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

The length of segment AB is:

AB = \sqrt{(6 - 0)^2+(0 - 7)^2} = 9.2

The length of segment BC is:

BC = \sqrt{(6 - 3)^2+(0 + 4)^2} = 5

The length of segment CD is:

CD = \sqrt{(-3 -3)^2+(-4 + 4)^2} = 6

The length of segment DE is:

DE = \sqrt{(-6 + 3)^2+(0 + 4)^2} = 5

The length of segment EA is:

EA = \sqrt{(-6 +0)^2+(0 - 7)^2} = 9.2

Hence the perimeter is:

P = AB + BC + CD + DE + EA = 9.2 + 5 + 6 + 5 + 9.2 = 34.4 units.
