Let x2 + 4y2 = 16. Which expression represents d^(2y)/dx^2 ?

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2 acellus answer

Point a (7,3) is translated to a'(16,-9). which rule describes the translation?

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
