GRAPHIC SET COMPLETION OF THE VARIABLE LINEAR INEQUALITIES

Graph linear inequalities himpunanan completion of one variable already discussed when we learn mathematics in junior high. However, to recall look at some examples below.
example 1
Determine the area of ​​the settlement of
a. X ≥ 0
b. Y ≥ 0
c. X <2
d. X ≥ -1
e. 2 ≤ x ≤ 4
answer

a. X ≥ 0 has the equation x = 0, this is a straight line, which coincides with the y-axis. completion of the area can easily be searched the area of ​​the right y axis as required is for x ≥ 0. Settlement area is shown in Figure 4-2a.
b. Y ≥ 0 has the equation y = 0, this is a straight line that coincides with the x axis. settlement areas can easily be searched, the area on the top line or the x axis because the requested was for y ≥ 0. Settlement area is shown in Figure 4-2b
c. X <2 has the equation x = 2. Settlement area is the area to the left of the line because it is required for x <2. Settlement area is shown in Figure 4-2c
d. X ≥ -1 has the equation x = -1. Settlement area is the area to the right of the line as is required for x ≥ -1. Settlement area is shown in Figure 4-2d
e. 2 ≤ x ≤ 4 has equation x = 2 and x = 4. Settlement area is the area between the two lines. Derah completion is shown in Figure 4-2e
