23. Suppose a point (x, y) on the coordinate plane is rotated 270°
counterclockwise about the origin, then
reflected across the line
y=
-x, then reflected
across the y-axis.
Show that the image of (x, y) after this sequence of
transformations is the same as the image of
(x, y) after a 180° rotation about the origin.

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.

1 mph

step-by-step explanation:

if the question is asking how much does she drive per mile then,

13 / 13 = 1 mph
