Hello there,
To answer your question, the "and" within your statement represents the intersection of a graph of inequalities. We are looking for a number that is a solution to both compound inequalities. In your case, we want to look for a solution on the graph that is AT LEAST -8 and AT MOST 0. We know - 8 < 0 and we know 0 as our maximum value: x greater than equal to -8, x less than equal to 0, or -8 < x < 0
