<em>Brainlists please</em></h2>
It is 2 12/20 simplified is 2 6/10 simplified is 2 3/5
So if you want it simplified it is 2 6/10 but if you just want the answer I think it would be 2 3/5
Hope this is helpful
And have a great day
Answer:
x = 7.8
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + 2^2 = c^2
16 + 4 = c^2
c^2 = 20
c = 4.5
a^2 + b^2 = c^2
a^2 + 4.5^2 = 9^2
a^2 + 20.25 = 81
a^2 = 81 - 20.25
a^2 = 60.75
a = 7.8

Answer: x = 0</h3>
Work Shown:
y = -3x^2 - 12 is the same as y = -3x^2 + 0x + (-12)
Compare this to y = ax^2 + bx + c, and we'll find that
a = -3
b = 0
c = -12
Plug the 'a' and 'b' values into the formula below and simplify
h = -b/(2a)
h = -0/(2*(-3))
h = 0
The x coordinate of the vertex is x = 0, so the axis of symmetry is also x = 0.
The axis of symmetry lays perfectly on top of the y axis.
