Plz explain your answer! i will mark at !

A: triangle PQR is transformed into triangle P'Q'R' by a scale of 1/2, because all coordinates of PQR multiple by 1/2 produce corresponding coordinates in P'Q'R'

B. when reflected across the y axis, the y values don't change, the x values become the opposites, so (-4,0), (-3,1), (1,-2)

C. No, they are not congruent. They are similar, but not congruent. A dilation produces congruent shapes. the side length of P''Q''R'' is only half of the side length of PQR

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
