Answer:
n = -5.4
Step-by-step explanation:
−7.24 + 4.8n − 4.77 = −0.67 + 6.9n
Subtract 4.77 from −7.24 to get −12.01.
-12.01 + 4.8n = -0.67 + 6.9n
Subtract 6.9n from both sides
-12.01 + 4.8n - 6.9n = 0.67
Combine 4.8n and −6.9n to get −2.1n
-12.01 = 2.1n = -0.67
Add 12.01 to both sides.
-2.1n = -0.67 + 12.01
Add −0.67 and 12.01 to get 11.34.
−2.1n = 11.34
Divide both sides by −2.1.
n =

Answer:
Explanation given below.
Step-by-step explanation:
The first step is to put the parabola in the form , which is the <em>standard form of a parabola</em>
<em />
<u>Note:</u> a is the coefficient before x^2 term, b is the coefficient before x term, and c is the independent constant term
The axis of symmetry divides the parabola symmetrically. The axis of symmetry has the equation
Where <em><u>a and b are the respective values shown above</u></em>
<em><u /></em>
So, that is how you get the axis of symmetry of any parabola.
