The vertices of triangle ABC are A(1.1), B(1,5), and C(7.1). If triangle ABC is reflected across the x-axis to create triangle A'B'C', what would be the new coordinates for the vertices of this new triangle? А
A' (1-1), B(5-1), C (-1,-7)
B
A' (1-1), B(-1,-5), C (-7,-1)
С
A' (-1,1), B (-1,5), C (-7.1)
D
A' (1-1), B(1,5), C (7.1)

Step-by-step explanation:

Hi hi ‍♀️

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
