△rst is mapped to △r′s′t′ using the rule (x, y)→(x,−y) followed by (x, y)→(3x,3y)

which statement correctly describes the relationship between △rst
and △r′s′t′ ?

a.) △rst is not congruent to △r′s′t′ because the rules do not represent a sequence of rigid motions.
b.) △rst is congruent to △r′s′t′ because the rules represent a rotation followed by a translation, which is a sequence of rigid motions.
c.) △rst is congruent to △r′s′t′ because the rules represent a reflection followed by a rotation, which is a sequence of rigid motions.
d.) △rst is congruent to △r′s′t′ because the rules represent a reflection followed by a translation, which is a sequence of rigid motions.

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
