The ratio of 1 to 3 is 1 : 3 or 1/3 (1 over 3)
The correct answer for the question shown above is the second option (Option b), and the option cwhich is:
b) x = -1/16y^2
c) y=-1/16x^2
The explanation is shown below:
The focus of a parabola is (h,k+1/4a), then, you have:
h,k= (0,0)
1/4a=1/4(-1/16)
Then, you obtain:
1/4a=-4
Therefore, the focus of the equation of the parabola x = -1/16y^2 and the parabola y=-1/16x^2 <span>is F(0-4)

So, as you can see, the correct answer is the options mentioned before, the option b and the option c.
Answer:
x= -1
y= 1
Step-by-step explanation:
Set both equations equal to each other
2x+3=x^2+3x+3 then solve for x
2x=x^2+3x the 3 on either side cancel out
-x=x^2
-1=x
Then plug -1 in for one of the equations to solve for y
Y=2(-1)+3
Y=1
\left[x \right] = \left[ 2\,y\right][x]=[2y] graphic do ur sheets
