Answer:
![b=-3](https://tex.z-dn.net/?f=b%3D-3)
Step-by-step explanation:
The given function is
.
When we compare to
, we have
and c=10
The equation of the axis of symmetry of a vertical parabola is:
![x=-\frac{b}{2a}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7Bb%7D%7B2a%7D)
Also from the question the axis of symmetry is x=6
We substitute the values to get:
![6=-\frac{b}{2*\frac{1}{4}}](https://tex.z-dn.net/?f=6%3D-%5Cfrac%7Bb%7D%7B2%2A%5Cfrac%7B1%7D%7B4%7D%7D)
![6=-\frac{b}{\frac{1}{2}}](https://tex.z-dn.net/?f=6%3D-%5Cfrac%7Bb%7D%7B%5Cfrac%7B1%7D%7B2%7D%7D)
![b=-\frac{1}{2}*6](https://tex.z-dn.net/?f=b%3D-%5Cfrac%7B1%7D%7B2%7D%2A6)
![b=-3](https://tex.z-dn.net/?f=b%3D-3)
Answer:
∠s = ∠v
Step-by-step explanation:
Supplementary angles add up to 180°
∠s + ∠v = 180
90 + ∠v = 180
∠v = 180 - 90
∠v = 90°
⇒∠s ≅ ∠v
Answer:
(-4,6)
Step-by-step explanation:
When rotating 90 degrees counter clockwise you go from (x,y) to (-y,x)
First start by adding 2 to 4
then add 3 to 1
(6, 4)
then use the formula (-y,x) to change (6,4)
(-4,6)
