Recall from lesson 6 that the semi-major axes of an ellipse are the segments from the center to the farthest
vertices, and the semi-minor axes are the segments from the center to the closest vertices. for each of the ellipses
in problem 1, find the lengths a and b of the semi-major axes.

Could these triangles be congruent? yes, if ab - deyes, if bc = 7yes, if ab - efno, because the hypotenuses must have different lengths

Figure abcd is a trapezoid with point a (0, -4). what rule would rotate the figure 270° clockwise, and what coordinate would be the output for point a'?

Which explains whether or not the values in the table represent a direct variation? x 4 6 10 20 y 1 1.5 2.5 5 the table represents a direct variation because the values are proportional. the table represents a direct variation because the values are nonproportional. the table does not represent a direct variation because the values are proportional. the table does not represent a direct variation because the values are nonproportional.
