Answer:

x=-5

Step-by-step explanation:

Lets take 2(x+1) first

carry on the 2 to the parenthesis

2 . x & 2 x 1

=2x+1

next we put it back in the equation

x-4=2x+1

cancel out the common terms

for example when you bring the +1 to the other side it will become -1

now we will do -4(-1)

=-5

rewrite the equation:

x-5=2x

do the same with the x! :)

equation:2x-x

=x (or 1x)

so -5=x

thats your answer!

x=-5

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.
