Evaluate x2 + 4x + 1 when x = -3

How do the graphs of y = 1/x and y=5/x+6 compare?

You can find the constant of proportionality by finding the ratio of

The diagonals of a quadrilaretral intersect at (-1,4). one of the sides of the quadrilateral is bounded by (2,7) and (-3,5) determine the coordinates of the other side in order for the quadrilaretral to be a square.
