Answer:
no
Step-by-step explanation:
Put 2 where x is and see if you get a true statement.
1/2(2) -4 = 5
1 -4 = 5
-3 = 5 . . . . . . False
2 is not a solution to the equation.
__
The solution is x=18.
Answer:
The answer is 21
Step-by-step explanation:
21x4+2=86
Step-by-step explanation:
Since we have a vertical directrix, the equation of the parabola is

Where p is the distance from the vertex to the directrix.
or the distance from the vertex to the focus.
Since we have a sideways parabola, let use the point for the directrix is (-6,0). So let find the midpoint of (-6,0) and (6,0). That would be our vertex.


So our vertex is (0,0).
So our equation become

The distance from the focus and directrix is 6.
So p=6.

So p is 6.
Since p is 6,
