13/28 is the answer to this mathematical equation
$48.865 per headphone
<u>unit rate</u> : total cost/total items
unit rate:
390.92/8
48.865
Each headphone costs $48.865
The answer is A,
Your farthest x value is -2
Answer:
53 + 1 = 54
give me brainllest if this is right okay?

Answer: x = -1</h3>
Explanation:
The given quadratic is in the form y = ax^2 + bx + c
We have a = 1, b = 2, c = 2
This then leads to
h = -b/(2a)
h = -2/(2*1)
h = -1
This is the x coordinate of the vertex (h,k)
The axis of symmetry is the vertical line passing through the vertex. So it must share the x value in question.
Meaning the axis of symmetry is x = -1. Every point on this vertical line has an x coordinate of -1. This line of symmetry splits the parabola into two equal mirrored halves.
I recommend using a graphing tool like Desmos to visually confirm the answer.
