At the airport, each piece of luggage to be checked in must not weigh more than 50 pounds. Use W to represent the weight (in pounds) of a piece of luggage that can be checked in

W <= 50

Step-by-step explanation:

Since the luggage cannot be over 50 pounds, that means that the weight of the luggage can be 50 pounds or less which is written as W <= 50 ("W is less than or equal to 50").

what's that

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
