Answer:

(3, 3) and (15, 15)

Step-by-step explanation:

The points equidistant from the given point and the y-axis lie on the parabola that has (3,6) as its focus and the y-axis as its directrix. The equation for that can be simplified from ...

(x -3)^2 +(y -6)^2 = x^2

-6x +9 +y^2 -12y +36 = 0 . . . . . subtract x^2, eliminate parentheses

We can find the points that lie on the line y=x (equidistant from both axes) by substituting y for x or vice versa. Then we have the quadratic ...

x^2 -18x +45 = 0 . . . . substitute x for y and collect terms

(x -3)(x -15) = 0 . . . . factor it

x = 3 or 15

So, the points of interest are (x, y) = (3, 3) and (x, y) = (15, 15).

<h3>Answer:</h3>

99.90%

<h3>Step-by-step explanation:</h3>

STEPS:

Find the total amount
Find out what number of what we want to know the percentage of there are out of the whole amount there is. (Divide the percentage amount we want to find by the total amount)
Turn into a percentage by multiplying by 100

Find the total sum

30.2 mil = 30,200,000 small businesses + 30,000 other = 30,230,000 total

Find the fraction that small businesses make up of the total

$\frac{small~businesses}{total~businesses} = \frac{30,200,000}{30,230,000} = 0.9990$
