Answer:

Reflection across the x-axis composition translation of negative 6 units x, negative 2 units y

Explanation:

The reflection across the x axis would produce A'B'C' then the translation of -6 units x and -2 units y would move the shape to A"b"C"

Answer:

<h2>Reflection across the x-axis composition translation of negative 6 units x, negative 2 units y.</h2>

Step-by-step explanation:

To find the right order in this transformations from ΔABC to ΔA"B"C", we first need to consider that the initial figure is ΔABC, which is transformed to ΔA'B'C', and then to ΔA''B''C''.

So, from the image we can see that from ΔABC to ΔA'B'C', the transformation applied is reflection across the x-axis, because ΔA'B'C' is an inverted image of the original, like a mirror.

Then, from ΔA'B'C' to ΔA''B''C'', we can see that the transformation is a combination of translations, to the left side and down side. From the graph we can see that it moved exactly, 6 negative units in the direction of the x-axis, and 2 negative units in the direction of the y- axis, in other words, it moved 6 units to the left and 2 units down.

Therefore, the correct answer is the second one:

Reflection across the x-axis composition translation of negative 6 units x, negative 2 units y.

Ira Lisetskai [31]

Answer:

Points B and C are opposite

Step-by-step explanation:

0 on the number line marks the center of the number line. To the right on the number line are positive integers and to the left from zero are negative integers.

Points B and C are opposite because they are each half way between 0 and 1 on the right and 0 and -1 on the left
