For the first image can you give us the choices for each one?
375/1000. You can then reduce that to get 3/8. So the answer is 3/8
1/5
Y2 -Y1
____
X2-X1
5-4=1 = 1
________
2- - 3 = 5
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.
