Answer:
(-b/2a, b^2/(4*a) - b^2/2a + c)
Step-by-step explanation:
For a general parabola:
y = a*x^2 + b*x + c
We can write the vertex as:
(h, k)
The x-value of the vertex is the value of the axis of symmetry.
Then we have:
h = x = -b/2a
Now we need to find the y-value of the vertex.
To do that, we just replace the variable "x" by the x-value of the vertex in our equation, so we get:
k = y = a*(-b/2a)^2 + b*(-b/2a) + c
k = b^2/(4*a) - b^2/2a + c
Then the coordinates of the vertex are:
(h, k) = (-b/2a, b^2/(4*a) - b^2/2a + c)
Answer:
X= 5 ( 2 + Y )❤️
Step-by-step explanation:
- X = 5y + 10
- 2x-10y= 20
- 2( X - 5y ) = 20
- (x-5y ) = 20/2
- X - 5y = 10
- X= 10 + 5y
- X = 5 ( 2 + Y )

Step-by-step explanation:
Answer:
BC : BN = 8 : 3
Step-by-step explanation:
Parallel lines divide any transversal into segments with the same ratio. That means ...
... BN : NC = AM : MD = 3 : 5
Since BC = BN + NC, the desired ratio is ...
... BC : BN = (BN+NC) : BN = (3+5) : 3
... BC : BN = 8 : 3
