Solve -2a-5 3. which graph shows the solutions?

Step-by-step answer

P Answered by PhD

52

The solution to the inequality is -2a-5>3 is a < -4

The graph that represents the solution has been attached

The given inequality is:

-2a - 5 > 3

Add 5 to both sides of the inequality

-2a - 5 + 5 > 3 + 5

-2a > 8

Divide both sides by 2

$\frac{-2a}{2} \frac{8}{2} \\\\-a 4$

Multiply both sides by -1 and change the inequality sign from > to <

-1(-a) < -1(4)

a < -4

The graph that shows the solution of the inequality is attached below

Check attached graph

Step-by-step explanation:

Given inequality is -2a-53 .

Now we need to graph the given inequality to find the correct choice.

-2a-53

-2a-5+53+5

-2a8

$-\frac{2a}{-2}$

that means line will go on the left side of -4.

since we have <, so there will be an open circle at -4.

Hence final graph of the given problem looks like:

Write a compare and contrast analysis of how "Broken Chain" and "Fish Cheeks" both address a common theme about belonging. I have 2 paragraphs and i need one more to put in the middle. here are my paragraphs: The Broken Chain and Fish Cheeks both share the same story, and that’s the story of belonging. Both these literary works have a theme of "belonging" in the sense that it is interpreted differently.In the Broken chain, people have to learn to love and appreciate other people, while in Fish Cheeks speaks about people who like their culture. In both stories, the physical appearance is very important fo the characters, as they are trying to change the looks to make people like them.

The characters want to change themselves n order to please people. However, the belonging will not happen if you change the physical looks. In these literary works, everyone has something in common, no matter how they look, and that everyone should be treated nicely. The person shouldn’t follow the rules blindly, because that way the person is losing himself and his integrity.
