Let's see it...

-x+0+(-x)=0 ???

There is a + before the parenthesis, the sign is the same.

-x+0-x = 0

Since the x have equal sign, we add them to get -2x

We have 2x - 0 = 0

Move the zero to the right, so 2x = 0

Divide both for 2...

x = 0

Substitute 0 to x, so -0+0+(-0) = 0

0 = 0 the statement is true

Which rule deacribes the

Marysya12 [62]

Answer:

A. ${T_{-6,-2}}\circ {r_{x-axis}}(x,y)$

Step-by-step explanation:

We have that, ΔABC is transformed to get ΔA''B''C''.

We see that the following transformations are applied:

1. Reflection across x-axis i.e. flipped across x-axis.

Now, ΔABC is reflected across x-axis along the line AC to get ΔA'B'C'.

2. Translated 2 units down i.e. shifted 2 units down and and then translated 6 units to the left i.e. shifted 6 units to the left.

So, ΔA'B'C' is translated 2 units downwards and 6 units to the left to get ΔA''B''C''.

Hence, the sequence of transformations is Reflection across x-axis and then Translation of 2 units down and 6 units left.
