Answer:
The vertex of the parabola is (-2,0)
Step-by-step explanation:
The given function is:

Now, in order to find the vertex for the parabola, that is v(h,k), comparing the above equation with the standard form of equation that is
, we get
a=-3, b=-6 and c=0
We know,
and
, therefore
and 

Thus, the vertex is given as:(h,k)=(-2,0).
Answer: 25
Step-by-step explanation:
Answer:
the sume of two numbers is 2. if one number is subtracted from the other, their difference is 8. find the numbers---->
Step-by-step explanation:
X+Y=2
X-Y=8
If you subtract X+Y with X-Y, you get 2y, and so that equals 2-8, that is -6.
2y=-6
y=(-6)/2
y=-3
-3+X=2
x=2+3
x=5 and y=-8
Check
-3+5=2
5-(-3)=8
