The figure shows two intersecting chord, thus this simply can be solved using the Intersecting Chord Theorem, which states that "<span>When two chords intersect each other inside a circle, the products of their segments are equal."
Thus,
(5mxn=15mx2m)
n=6m</span>
For this case we have the following functions:

We must find
By definition of composition of functions we have:

So:
![(p-9) (x) = x ^ 2-1- [5 (x-1)] = (x ^ 2-1) -5 (x-1)](https://tex.z-dn.net/?f=%28p-9%29%20%28x%29%20%3D%20x%20%5E%202-1-%20%5B5%20%28x-1%29%5D%20%3D%20%28x%20%5E%202-1%29%20-5%20%28x-1%29)
Thus, the correct option is option C.
Answer:

Option C
Answer:
X = 13
y= 54
Step-by-step explanation:
9x-7=7x+19 (vertical opposite angle)
9x-7x=19+7
2x=26
X=13°
now ,
(9x-7)= 9x13-7=110
(9x-7)+(y+16)=180 sum of the straight angle
110+y+16=180
y=54
