ABC is reflected across x = 1 and y = -3. What are the coordinates of the reflection image of B after both reflections?A. (-7, -

Dima020 [189]

Answer:

The correct option is C.

Step-by-step explanation:

From the given figure it is noticed that the coordinates of B are (-5,-7).

If ABC is reflected across x = 1, then

$(x,y)\rightarrow(1-(x-1),y)$

$(x,y)\rightarrow(2-x,y)$

$(-5,-7)\rightarrow(2+5,-7)$

$(-5,-7)\rightarrow(7,-7)$

If ABC is reflected across y =-3.

$(x,y)\rightarrow(x,-3-(y-(-3)))$

$(x,y)\rightarrow(x,-6-y)$

$(7,-7)\rightarrow(7,-6-(-7))$

$(7,-7)\rightarrow(7,1)$

Therefore option C is correct.

What is mythology and therefore why is it important?

Mrrafil [7]

Answer:

mythology is important for both individualistic and collective reasons. On an individual level, mythology could teach moral or human truths, whereas on a collective level mythology could be used to keep people in touch with their origins. Mythological stories could then be used to teach children values such as hard work, diligence and obedience.
