Answer:
y=10x-2x ................
Answer:
(1,1)
Step-by-step explanation:
Since y=x, we can say x=x^2-x+1. This means x^2-2x+1=0. x=1, y=1, thus your solution is (1,1).

<h3>What is trigonometry?</h3>
The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.
The trigonometric function for an angle
is
![tan\theta = tan\dfrac{\pi}{4}=1\ \ \ \ Cos \theta=Cos\dfrac{\pi}{4}=\dfrac{\sqrt{2}}{2}\ \ \ \ Sin\theta =Sin\dfrac{\pi}{4}= \dfrac{\sqrt{2}}{2}](https://tex.z-dn.net/?f=tan%5Ctheta%20%3D%20tan%5Cdfrac%7B%5Cpi%7D%7B4%7D%3D1%5C%20%5C%20%5C%20%5C%20Cos%20%5Ctheta%3DCos%5Cdfrac%7B%5Cpi%7D%7B4%7D%3D%5Cdfrac%7B%5Csqrt%7B2%7D%7D%7B2%7D%5C%20%5C%20%5C%20%5C%20Sin%5Ctheta%20%3DSin%5Cdfrac%7B%5Cpi%7D%7B4%7D%3D%20%5Cdfrac%7B%5Csqrt%7B2%7D%7D%7B2%7D)
The trigonometric function for an angle
will be:-
![tan\theta=tan \dfrac{\pi}{6}= \dfrac{1}{\sqrt3}}\ \ \ \ \ Sin\theta =Sin\dfrac{\pi}{6}= \dfrac{1}{2} \ \ \ \ \ Cos \theta = Cos\dfrac{\pi}{6}= \dfrac{\sqrt{3}}{2}](https://tex.z-dn.net/?f=tan%5Ctheta%3Dtan%20%5Cdfrac%7B%5Cpi%7D%7B6%7D%3D%20%5Cdfrac%7B1%7D%7B%5Csqrt3%7D%7D%5C%20%5C%20%5C%20%5C%20%5C%20Sin%5Ctheta%20%3DSin%5Cdfrac%7B%5Cpi%7D%7B6%7D%3D%20%5Cdfrac%7B1%7D%7B2%7D%20%5C%20%5C%20%5C%20%5C%20%5C%20%20Cos%20%5Ctheta%20%3D%20Cos%5Cdfrac%7B%5Cpi%7D%7B6%7D%3D%20%5Cdfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D)
Therefore the trigonometric function for an angle
