Answer and Step-by-step explanation:
We are told that AB is equal to 3x + 1.
BC is then half of AB, or .
AC is then 4 less than BC, or
To find the perimeter, we add all of these together.
3x + 3x/2 + 3x/2 = 6x
1 + 1/2 + (1/2 - 4) = -2
The final answer is 6x - 2.

Answer:
<h2>Vertical stretch or compression and vertical shift.</h2>Step-by-step explanation:
When we talk about the transformation of functions, we can mention stretching, rotating, dilating, shifting. However, when we want to transform linear functions, there are only two transformations that are worthy in that case, those are vertical stretch or compression and vertical shift.
Now, you may ask, why only vertical transformation? the reason behind that is because horizontal transformation would give the exact same result because it's only a straight line which we are transforming.
Another common question would be, why only two transformations? it's because with these two you can get all the results because it's a straight line.
The image attached shows examples of this.
