what is the common domain and range of y≤1,y>-2/3x-2 and y>2/3x-2?

y≤1

and why do you post it twice, and not correct the error?

I apologize for the error. Here is the corrected answer:

The common domain for all three inequalities is all real numbers (-∞,∞).

The range for y≤1 is (-∞,1].

For y>-2/3x-2, the range is y>-2/3x-2, which means all y-values greater than -2/3x-2 are included.

For y>2/3x-2, the range is y>2/3x-2, which means all y-values greater than 2/3x-2 are included.

Therefore, the common range for all three inequalities is y> -2/3x-2.
