It seems that the boy uses everyday language in order to describe what he sees and smells. By resorting to this, the reader gets the perspective of a young boy from a poor social class because the imaginary used is based on elements that he might see on daily bases, smells like the cat or somthing roaten are really common in the streets.
Y - 4x ≤ -6y - 4x ≤ -6
We add 6y and 4x to each equality
7y ≤ 0 ≤ 6y + 4x -6
Observing:
7y ≤ 0, we see that the values of y can be only negative or 0, not positive.
So we are left with (-2,-14) (-1,-9) (0,-5)
We check the second equality:
6y + 4x - 6 ≥ 0 for these 3
None of the inequalities satisfy the given expressions simultaneously.
The choice that avoids run-on sentences to present the information clearly and correctly is, "Levi wanted to save the endangered sparrows. He built a birdhouse, and he passed out flyers. He also hung signs to tell people to keep their cats inside." To avoid run-on sentences, the writer limited the use of conjunctions to avoid confusion and instead, divided it into three sentences.
