Answer:
(2, - 2 )
Step-by-step explanation:
4x - y = 10 → (1)
x - 4 = y → (2)
substitute x - 4 = y into (1)
4x - (x - 4) = 10 ← distribute parenthesis on left side by - 1
4x - x + 4 = 10
3x + 4 = 10 ( subtract 4 from both sides )
3x = 6 ( divide both sides by 3 )
x = 2
substitute x = 2 into either of the 2 equations and solve for y
substituting into (2)
2 - 4 = y
- 2 = y
solution is (2, - 2 )
Vertex of parabola is y=
at (4,6)
Step-by-step explanation:
The given equation of parabola is y= 
Simplifying the equation,
y= 
y= 
y= 
y= ![(-1)[(x^{2} -8x + 16)-(16-22)]](https://tex.z-dn.net/?f=%28-1%29%5B%28x%5E%7B2%7D%20-8x%20%2B%2016%29-%2816-22%29%5D)
y= ![(-1)[(x-4)^{2}+(+6)]](https://tex.z-dn.net/?f=%28-1%29%5B%28x-4%29%5E%7B2%7D%2B%28%2B6%29%5D)
y= 
y= 
The general equation of parabola is y = y= 
Where, (h,k) is vertex of parabola.
On comparing the equations
we get,
Vertex of parabola is y=
at (4,-6)
