Answer: x= -0.2
Step-by-step explanation:
Given
LM = 9, MN = 6x, and LN = 9x
Find
LN
Explanation
as we see LN = LM + MN
so ,
![\begin{gathered} 9+6x=9x \\ 9=9x-6x \\ 9=3x \\ x=3 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%209%2B6x%3D9x%20%5C%5C%209%3D9x-6x%20%5C%5C%209%3D3x%20%5C%5C%20x%3D3%20%5Cend%7Bgathered%7D)
so , LN = 9x = 9 * 3 = 27
Final Answer
Therefore , the length of LN is 27

Answer:
y ≥ 2x-2
Explanation:
y-intercept is -2 and slope is 2. The line is solid and it is shaded above so it would be greater than or equal to.
The sum of this problem is 10,030
