Answer:
The vertex would be (-1, -5).
Step-by-step explanation:
In order to find this, first find the x-coordinate of the vertex. You can do this by calculating out -b/2a in which a is the coefficient of x^2 and b is the coefficient of x.
-b/2a
-(-2)/2(-1)
2/-2
-1
So we know the x-coordinate to be -1. Now we plug that into the equation and find the y value.
-x^2 - 2x - 6
-(-1)^2 - 2(-1) - 6
-(1) + 2 - 6
-5
We are going to add.
80+48=128. So the perimeter is 128. Hoped I helped. :)
His location would be 20 feet above the sea level because...
30+-10= 20 because adding a negative to a positive is basically like subtracting.

Answer:
b
Step-by-step explanation:
Answer:
7x - 3 = 60
7x = 63
x = 9
if you need to find for y
11y + 5 = 60
11y = 55
y = 5
