Answer:
x=2
Step-by-step explanation:
The axis of symmetry can be calculated using the following formula:
In order to use this formula, we need to have the function written in it's polynomial formula:
In order to do so, we have to isolate Y from the excercise's formula.
Then we resolve the square of the binomial knowing that (a+b)^2=a^2+2.a.b+b^2
Now we have that:
As we have now the polynomyal formula, we know that a=-2, b=8 and c=-13. We supplant on the formula and get:
Answer:
Yes there is enough information to find both triangles DEF and DHG are congruent.
Both the triangles are congruent by SAS theorem of congruence.
Step-by-step explanation:
Lets have a look to both of the triangles.
And mention what are the given information in our question.
We have DEF and
DHG.
Where
- FD
DG
- ED
And we can see that (Vertically opposite angles).
So we have two sides equal and an angle between the two are equal.
Then we can say that through SAS property of congruence DEF and
DHG are congruent
