How did they go from =-9/2(x+6) to =-9/2x-54/2 ???

Hi, I don't know if you still need the answer, but here you go:

They used distributive property.

Step-by-step explanation:

They multiplied -9/2 times "x" and then, times "+6".

First, you get -9/2x for the first term in the parenthesis.

Second, you multiply -9/2 times 6 in the form of a fraction.

* When multiplying fractions, you multiply straight across so:

-9/2 × 6/1 = -54/2

Leaving you with:

-9/2x-54/2

The -54/2 simplifies into -27, which gives you:

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
