49.47 un² is your final answer since you are supposed to round to the tenths place. I hope this helps.
Answer:
B
Step-by-step explanation:
Answer:
Coordinates of B is (3,-4)
Step-by-step explanation:
You multiply -2 by 2 to get -4 and then create the equation
then you substitue -7 for +7 and add +7 to -4 which gives you 3 (x coordinate of B)
You multiply -1 by 2 to get -2 and then create the equation
then you subtract 2 by -2 which gives you -4 (y coordinate of B)
To check your answer use the midpoint formula 
which will give you the midpoint (-2,-1)
C it is the graph of y=in x translated 7 units up 3 units to the right
