Let p=(x, y) be a point on the graph of y=x2−9. (a) express the distance d from p to the origin as a function of x.

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.

Two numbers have a sum of -19. one number is x. what expression represents the other number?
