Answer:
(9, -8)
step-by-step explanation:
- original coordinates of B: (-9, -8)
if reflected over y-axis, use the formula: (x, y) → (-x, y)
- new coordinates: (-(-9), -8) → (9, -8)

does anybody know
79.55/8.6=9.25
The answer is 9.25
Answer:
The correct answer is C.
Step-by-step explanation:
The given equation is;
![r=\frac{1}{1-\sin(\theta)}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B1%7D%7B1-%5Csin%28%5Ctheta%29%7D)
This implies that;
![r(1-\sin(\theta)=1](https://tex.z-dn.net/?f=r%281-%5Csin%28%5Ctheta%29%3D1)
![r-r\sin(\theta)=1](https://tex.z-dn.net/?f=r-r%5Csin%28%5Ctheta%29%3D1)
Let us write in Cartesian coordinates by substituting;
![r=\sqrt{x^2+y^2} ,y=r\sin(\theta)](https://tex.z-dn.net/?f=r%3D%5Csqrt%7Bx%5E2%2By%5E2%7D%20%2Cy%3Dr%5Csin%28%5Ctheta%29)
![\sqrt{x^2+y^2}-y=1](https://tex.z-dn.net/?f=%5Csqrt%7Bx%5E2%2By%5E2%7D-y%3D1)
![\sqrt{x^2+y^2}=y+1](https://tex.z-dn.net/?f=%5Csqrt%7Bx%5E2%2By%5E2%7D%3Dy%2B1)
Square both sides;
![(\sqrt{x^2+y^2})^2=(y+1)^2](https://tex.z-dn.net/?f=%28%5Csqrt%7Bx%5E2%2By%5E2%7D%29%5E2%3D%28y%2B1%29%5E2)
This implies that;
![x^2+y^2=y^2+2y+1](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3Dy%5E2%2B2y%2B1)
![x^2=2y+1](https://tex.z-dn.net/?f=x%5E2%3D2y%2B1)
![y=\frac{1}{2}x^2-\frac{1}{2}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B2%7Dx%5E2-%5Cfrac%7B1%7D%7B2%7D)
This is an equation of a parabola that opens upwards with a y-intercept of
.
The correct choice is C
