For the given parabola, the axis of symmetry is x = 2.
<h3>
How to get the axis of symmetry?</h3>
For any given parabola, we define the axis of symmetry as a line that divides the parabola in two equal halves.
For a regular parabola, we define the axis of symmetry as:
x = h
Where h is the x-component of the vertex.
Remember that for the general parabola:
y = a*x^2 + b*x + c
The x-value of the vertex is:
h = -b/(2a)
Then for the function:
f(x)=−2x²+8x−2
We get:
h = -8/(2*-2) = 2
Then the axis of symmetry is x = 2.

Answer:
1. 55.5
2. 54.5
Step-by-step explanation:
Use division to convert the fraction to a decimal:
1/4 = 1 ÷ 4 = 0.25
Multiply by 100 to get percent value:
0.25 × 100 = 25%
Answer:
Step-by-step explanation:
11. 76x + 23x = 33
99x = 33
x = 33/99 which reduces to 3
12. 140r - 8r - 4r = 216
128r = 216
r = 216/128 which reduces to 27/16
13. 98c - 99c = 1
-1c = 1
c = -1/1
c = -1
14. 104mn + (-84mn) = 36
104mn - 84mn = 36
20mn = 36
mn = 36/20 which reduces to 9/5....I am not sure about this one...I was not sure if u were looking for m or n..so I didn't separate them. But if ur looking for m, it is m = 9/5n...and if ur looking for n, it is n = 9/5m
15. 118j - 234j = 234
- 116j = 234
j = -234/116 reduces to - 117/58
If you're asking the difference between 14 ft and 21 ft your answer is 7 ft, just subtract 14 from 21
Sorry I'm not sure if I'm right just my thinking...
set the number to be x so that (5x+2)(3x-4)??
