If you draw this on a number line, you would have an open circle or ( at -5 and your arrow will go to the right. You will have the same at 1 with your arrow going to the right.
Since it is "and" the answer is where they overlap.
the overlap begins at 1 and goes to infinity.
Interval notation: (1, infinity)
