The mean can be found by adding the two numbers and dividing by 2
let the second number be y
(x + y)/2 = 1/2x + 1
solve for y
multiply each side by 2
x + y = 2(1/2x + 1)
distribute
x + y = x + 2
subtract x on both sides
y = 2
ANSWER: the second number is 2
I believe you may have the order incorrect. If we were looking at g(f(x)) the answer would be 47. We would get this by sticking the 3 in for x in f(x) and solving, which would give us 48. We would then stick that answer in for x in the g(x), giving us 47.
In its current order the answer would be 28.
You have not shared the graphs from which you have to choose your answer.
Why not graph y=|x-4| yourself, to help you choose the correct answer?
First, graph y=|x|. It looks like a "v" opening up, with the vertex at (0,0).
Next, move the whole "v" graph 4 units to the right.
Compare your result to the given answer choices.

Step-by-step explanation:
For the given triangle, the value of x equals 30.9892 units.
Step-by-step explanation:
Step 1:
In the triangle, the angle is 40°, the opposite side has a length of 26 units, the adjacent side has a length of x units while the hypotenuse is not given.
To determine the value of x, we determine the value of the tan of the given triangle.
To calculate the tan of angle A we divide the opposite side's length by the the adjacent side's length.
![tan A = \frac{oppositeside}{adjacent side}.](https://tex.z-dn.net/?f=tan%20A%20%3D%20%5Cfrac%7Boppositeside%7D%7Badjacent%20side%7D.)
Step 2:
The length of the opposite side = 26 units.
The length of the adjacent side = x units.
![tan A = \frac{oppositeside}{adjacent side}, tan 40 = 0.8390, tan A = \frac{26}{x} .](https://tex.z-dn.net/?f=tan%20A%20%3D%20%5Cfrac%7Boppositeside%7D%7Badjacent%20side%7D%2C%20tan%2040%20%3D%200.8390%2C%20tan%20A%20%3D%20%5Cfrac%7B26%7D%7Bx%7D%20.)
![0.8390 = \frac{26}{x} , x = \frac{26}{0.8390} = 30.9892.](https://tex.z-dn.net/?f=0.8390%20%3D%20%5Cfrac%7B26%7D%7Bx%7D%20%2C%20x%20%3D%20%5Cfrac%7B26%7D%7B0.8390%7D%20%3D%2030.9892.)
So x measures 30.9892 units.
