We see it is the y terms squared so it opens left or right
in form
(y-k)^2=4(p)(x-h)
vertex is (h,k)
and p is distance from focus to vertex, also distance from vertex to directix
if p>0, then it opens to the right and dirextix is to the left of vertex
if p<0, then it opens to the left and directix is tothe right of vertex
so
(y-1)^2=4(4)(x-(-3))
vertex is (-3,1)
4>0 so dirextix is to left of vertex
left is in x direction
-3-4=-7
directix is x=-7
Answer:
Steps shown below
Step-by-step explanation:
We will simplify this using definitions and identities. Let's start.
Using 
, we have:
Using 
, we have:
Hence, proved.
It’s 6x6=36, because if 4 over 2 was 4 twice then 6 over 2 is 6 twice.
-4/5 and -1/2
Taking the LCM of the 2 fractions we get the common denominator 10
-8/10 and - 5/10
Now we can see the second fraction (-5/10) is bigger
Thus the friend is wrong
I believe the answer is A, I hope that helps
