Hello!</h2>
The answer is:
The fourth graph.
<h2>
Why?</h2>
We are given the following equation:

Then, we need to find the graph of f(x+2) that will be equal to:


Now, finding the x-axis interception, making "y" equal to 0, we have:


Therefore, the x-axis interception point is located at (-2,0), it matches with the fourth graph.
Now, finding the y-axis interception, making "x" equal to 0, we have:


Therefore, the y-axis interception point is located at (0,2), it matches with the fourth graph.
Hence, we have that the graph of f(x+2) is the fourth graph since the second graph function cuts the x-axis at -2 and the y-axis at 2.
Have a nice day!
In order to calculate LCD of 4/9 and 7/12, you need to calculate LCM of their denominators which is 9 and 12, it would be 36
In short, Your Answer would be 36
Hope this helps!
If you finish the question I may be able to answer it. ^^

Therefore they are perpendicular.</h3>
Step-by-step explanation:
A equation of line is
y =mx +c
Here the slope of the line is m.
Given equations are
x - 2y = 18
⇔-2y = -x +18
............(1)
and 2x + y = 6
⇔y = -2x +6 ............(2)
Therefore the slope of equation (1) is
= 
Therefore the slope of equation (2) is
= -2
If two lines are perpendicular, when we multiply their slope we get -1.
therefore,
=
. (-2) = -1
Therefore they are perpendicular.
