Answer: About -28.6 and -1.399.
Explanation:
To find the answer to this question, we will create a system of equations. Let x and y be the two numbers.
xy = 40
x + y = -30
Next, we will graph this system of equations. The point of intersection is the solution to our question. See attached for the graph. The two numbers are about -28.6 and -1.399.
