Answer:
The equation of the parabola is 
, whose real vertex is 
, not 
.
Step-by-step explanation:
A parabola is a second order polynomial. By Fundamental Theorem of Algebra we know that a second order polynomial can be formed when three distinct points are known. From statement we have the following information:
, 
, 
From definition of second order polynomial and the three points described above, we have the following system of linear equations:
(1)
(2)
(3)
The solution of this system is: 
, 
, . Hence, the equation of the parabola is . Lastly, we must check if belongs to the function. If we know that 
, then the value of 
is:
does not belong to the function, the real point is .
You said each equation but only posted one.
The standard form takes the place of
Ax + By = C.
y-5 = -3(x+2)
y - 5 = -3x - 6
y = -3x - 6 + 5
3x + y = -1
Done.
-2 - 24i, you can easily sum all real and imaginary parts to find this.
Alternatively, you can of course write -(2+24i)
So percent means parts out of 100
so 12%=12/100=1.2/10=0.12/1=0.12
3.84 is 12% of what
'of' means multiply
'is' means = sign
therefor
3.84=0.12 times what
divide both sides by 0.12
32=what
th enumber is 32
