Is there a series of rigid transformations that could map ΔRST to ΔXYT? If so, which transformations could be used? No, ΔRST and ΔXYT are congruent but ΔRST cannot be mapped to ΔXYT using a series rigid transformations. No, ΔRST and ΔXYT are not congruent. Yes, ΔRST can be reflected across the line containing RT and then rotated about T so that S is mapped to Y. Yes, ΔRST can be translated so that S is mapped to Y and then rotated about S so that R is mapped to X

Yes, ΔRST can be reflected across the line containing RT and then rotated about T so that S is mapped to Y.

Step-by-step explanation:

A rigid transformation is a transformation of the plane that preserves the exact properties of a given shape but there might be a change in its orientation.  It preserves the length, angles, and size of a given figure. In reflection, the image is the same size and shape as the given object.

For this question,  the best option is; yes, ΔRST can be reflected across the line containing RT and then rotated about T so that S is mapped to Y.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
