Short answer: 0.69Take 100. 31% = 31, 100-31=69Of course, when you increase the result by 31 percent you do not get the 100 back. But that was not the question.But, for completeness what do I multiply by to get the number, when adding 31 percent, gives me the original number, it is 0.7633 (1/1.31)

Your measure start at 16. So that is the basis (unless stated otherwise) upon which you reference the change.
That is:
16
20−16
is you fraction.
This gives:

For this to be a percentage we need the denominator such that it becomes 100. Thus we have:

To express this in the standard script form we have 25%

Answer:
x ≤1363
Step-by-step explanation:
2,000-637 = 1363
x ≤1363
Factor out a 6
6 / 6x^2 = x^2
6 / -12x = -2x
6 / -18 = -3
6(x^2 - 2x - 3)
Multiply the first term to the last
1 x -3 = -3
(a x b) = -3
(a + b) = -2 (middle term)
(1 x -3) = -3
(1 + -3) = -2
Plug them in by replacing -2x and simplify
6(x^2 - 1x - 3x - 3)
6((x^2 - 1x) - (3x - 3))
6(x(x - 1) - 3(x - 1))
6(x - 3)(x - 1)
Or in this case, 6(x - 1)(x - 3)
We need to write the equation in its vertex form so we have to know the general equation for the vertex form. It is written as:
y = (x - h)^2 + k
where h and k represents the point of the vertex.
We go as follows:
y = (x^2 + 4x) – 3
y +4= (x^2 + 4x+4) – 3
y = (x + 2)^2 - 7
Therefore, the correct answer from the choices is option B.
