Select the correct answer. Triangle ABC underwent a sequence of transformations to give triangle A′B′C′. Which transformations could not have taken place?

A.

a reflection across the line y = x followed by a reflection across the line y = -x

B.

a reflection across the x-axis followed by a reflection across the y-axis

C.

a rotation 180° clockwise about the origin followed by a reflection across the line y = x

D.

a reflection across the y-axis followed by a reflection across the x-axis

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

the answer is a

step-by-step explanation:

because your just changing the position of where the shape is

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
