Which system of linear inequalities is represented by the graph?
x – 5y < –5 and y < –2x – 4
x + 5y > 5 and y < 2x + 4
x – 5y < –5 and y < –2x + 4
x + 5y > 5 and y < 2x – 4

Step 1

Find the equation of the inequality of the solid red line

we know that

the equation of red the line is

The solution is the shaded area above the solid line (see the given graph)

therefore

the inequality is equal to

Step 2

Find the equation of the inequality of the solid blue line

we know that

the equation of the blue line is

The solution is the shaded area below the solid line (see the given graph)

therefore

the inequality is equal to

therefore

the answer is

The system of linear inequalities is equal to

and

using a graphing tool

the solution of the system is the shaded area in the attached figure

1/4 because there is 4 grades.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
