-7z - 7 ≤ -5z + 5
- 7 - 5 ≤ -5z + 7z
-12 ≤ 2z
-12/2 ≤ z
-6 ≤ z or z>= -6
It is composite because it can be factored out as 5x3 or 15x1
The answer is 4/1 you just have to divide 7 from both numbers and then you will get 4/1
I do believe it is 12 as well considering the fact that it's negative three and not positive. If it was a positive three then maybe it would be 18.
Answer:
The domain is all real numbers and the range is all real numbers as-well.
As x approaches infinity, so does y.
As x approaches -infinity, so does y.
