34/95.2 = YK/168
YK = 168 * 34 /95.2
YK = 60
so
x = 34 + YK
x = 34 + 60
x = 94
answer
x = 94 cm

Step-by-step explanation:
hope u find the answer
Domain:
f(x) has a denominator, which can't be zero. So, its domain is given by
![x^2-1\neq 0 \iff x^2\neq 1 \iff x\neq \pm 1](https://tex.z-dn.net/?f=x%5E2-1%5Cneq%200%20%5Ciff%20x%5E2%5Cneq%201%20%5Ciff%20x%5Cneq%20%5Cpm%201)
g(x) has a denominator as well. Moreover, it has a root. So, the content of the root can't be negative:
![x-1\geq 0 \iff x \geq 1](https://tex.z-dn.net/?f=x-1%5Cgeq%200%20%5Ciff%20x%20%5Cgeq%201)
And the denominator can't be zero:
![\sqrt{x-1}\neq 0 \iff x-1 \neq 0 \iff x \neq 1](https://tex.z-dn.net/?f=%5Csqrt%7Bx-1%7D%5Cneq%200%20%5Ciff%20x-1%20%5Cneq%200%20%5Ciff%20x%20%5Cneq%201)
So, the domain is ![x>1](https://tex.z-dn.net/?f=x%3E1)
Composition:
We have
![f(g(x))=\dfrac{g^2(x)}{g^2(x)-1} = \dfrac{\dfrac{1}{x-1}}{\dfrac{1}{x-1}-1} = \dfrac{\dfrac{1}{x-1}}{\dfrac{1-x+1}{x-1}} = \dfrac{\dfrac{1}{x-1}}{\dfrac{2-x}{x-1}}=\dfrac{1}{2-x}](https://tex.z-dn.net/?f=f%28g%28x%29%29%3D%5Cdfrac%7Bg%5E2%28x%29%7D%7Bg%5E2%28x%29-1%7D%20%3D%20%5Cdfrac%7B%5Cdfrac%7B1%7D%7Bx-1%7D%7D%7B%5Cdfrac%7B1%7D%7Bx-1%7D-1%7D%20%3D%20%5Cdfrac%7B%5Cdfrac%7B1%7D%7Bx-1%7D%7D%7B%5Cdfrac%7B1-x%2B1%7D%7Bx-1%7D%7D%20%3D%20%5Cdfrac%7B%5Cdfrac%7B1%7D%7Bx-1%7D%7D%7B%5Cdfrac%7B2-x%7D%7Bx-1%7D%7D%3D%5Cdfrac%7B1%7D%7B2-x%7D)
The domain of this function is
![2-x\neq 0 \iff x\neq 2](https://tex.z-dn.net/?f=2-x%5Cneq%200%20%5Ciff%20x%5Cneq%202)
But we also have to remember about the domain of g(x): if g(x) is undefined, we can't compute f(g(x))!
So, the domain of f(g(x)) is
![x>1\ \land x\neq 2](https://tex.z-dn.net/?f=x%3E1%5C%20%5Cland%20x%5Cneq%202)

Step-by-step explanation:
Answer:
<h2>5x - y = 3</h2><h2>5x - y - 3 = 0</h2>
Step-by-step explanation:
y = 5x - 3 <em>it's a slope-intercept form</em>
<em />
y = 5x - 3 <em>subtract 5x from both sides</em>
-5x + y = -3 <em>change the signs</em>
5x - y = 3 <em>it's a standard form</em>
<em />
5x - y = 3 <em>subtract 3 from both sides</em>
5x - y - 3 = 0 <em>it's a general form</em>
