If you subtract 2 from both sides
It would be 4=-4x
So the answer is B
Everything is divisible by five, so pull out five
5(-k^2+4k-6)
Answer:
(x,y) ⇒ (x - 3) (y - 4)
C(5, -1)

Answer:
Step-by-step explanation:
Given that a curve in polar coordinates is given by:
r=9+3cosθ
a) At point P, we have
![θ=\frac{21\pi}{18}](https://tex.z-dn.net/?f=%CE%B8%3D%5Cfrac%7B21%5Cpi%7D%7B18%7D)
Substitute to get
![r=9+cos \frac{21\pi}{18}\\=9.3932](https://tex.z-dn.net/?f=r%3D9%2Bcos%20%5Cfrac%7B21%5Cpi%7D%7B18%7D%5C%5C%3D9.3932)
b) Cartesian coordinate is
![x= rcos \theta=3.6934\\y =r sin \tjeta =8.6365](https://tex.z-dn.net/?f=x%3D%20rcos%20%5Ctheta%3D3.6934%5C%5Cy%20%3Dr%20sin%20%5Ctjeta%20%3D8.6365)
c) At the origin r =0
when r =0
we have
![9+3cos\theta=0\\cos\theta =-3](https://tex.z-dn.net/?f=9%2B3cos%5Ctheta%3D0%5C%5Ccos%5Ctheta%20%3D-3)
Since cos cannot take values as -3 it doe snot pass through origin.
\left[x \right] = \left[ \frac{5\,y}{158}+\frac{6\,z}{79}\right][x]=[1585y+796z]
