Answer:
B. -1
Step-by-step explanation:
If we have a parabola whose equation is:
The line of symmetry is calculated as:
Now, we have the equation 
and the line of symmetry is 
Where:
So, we can replace 
by -4 and 
by -2 and solve for 
using the following equation as:
It means that the equation of the parabola is equal to:
A. 5 invitations
b. 15 invitations
Comment if you need me to explain it.
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
you got it
<span>except keep going to get </span>
<span>x = ±√3025 </span>
<span>x = ± 55 </span>
<span>check: </span>
<span>275 , 55, 11 </span>
<span>is 55/275 = 11/55 ? YES </span>
<span>is -55/275 = 11/=55 ? YES</span>
First you see how it goes up 6 each time this is the start of your nth term rule
6n
Then -6 from the first term to get the ‘0th term’ 1-6=-5
So nth term rule is
6n-5
hope this helps
