(f/g)(x) = f(x)/g(x)
So the answer is C
I hope it will help
"Completing the square" is the process used to derive the quadratic formula for the general quadratic ax^2+bx+c=0. Suppose you did not know the value of a,b, or c of the quadratic...
ax^2+bx+c=0 You need a leading coefficient of one for the process to work, so you divide the whole equation by a
x^2+bx/a+c/a=0 now you move the constant to the other side of the equation
x^2+bx/a=-c/a now you halve the linear coefficient, square that, then add that value to both sides, ie, (b/(2a))^2=b^2/(4a^2)...
x^2+bx/a+b^2/(4a^2)=b^2/(4a^2)-c/a now the left side is a perfect square...
(x+b/(2a))^2=(b^2-4ac)/(4a^2) now take the square root of both sides
x+b/(2a)=±√(b^2-4ac)/(2a) now subtract b/(2a) from both sides
x=(-b±√(b^2-4ac))/(2a)
It is actually much simpler keeping track of everything when using known values for a,b, and c, but the above explains the actual process used to create the quadratic formula, which the above solution is. :)

Answer:
3x - y = 12 and x + 2y = - 10
Step-by-step explanation:
The first straight line passes through the points (2,-6) and (4,0).
Therefore, the equation of the straight line from two point form
⇒ y = 3(x - 4) = 3x - 12
⇒ 3x - y = 12 .......... (1)
Again, the second straight line passes through the points (2,-6) and (0,-5).
Therefore, the equation of this straight line will be
⇒ - 2(y + 5) = x
⇒ x + 2y = - 10 ......... (1)
Therefore, (1) and (2) are the system of equations. (Answer)
Answer:
The number line is attached.
Step-by-step explanation:
The holes are filled in since they are both inclusive of the value they hold, and there are two separate lines since they are broken apart by "or".
