Solve each system by substitution y=-5 5x+4y=-20

Suppose that g(x)=f(x+9) which statement best compares the graph of g(x) with the graph of f(x)

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.
