Let's split this up to make it easier.

Let's expand 5(2x - 1) first.

<u>Multiply </u>5 by 2x and - 1

5 × 2x = 10x

5 × -1 = -5

Now we have 10x - 5

Let'd do the other side

<u>Multiply </u>2 by 3x and -6

2 × 3x = 6x

2 × -6 = -12

Now we have 6x - 12

Let's combine both sides now.

<em>(10x - 5) + (6x - 12) </em>

Combine like terms:

10x + 6x = 16x

-5 + -12 = -17

Your final answer is 16x - 17

Hope I helped! Message me if you have any questions

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.
