What is the answer and how do you do this problem?
nadezda [96]

We want to recast the equation into the standard form equation for a circle centered at (h, k) with radius r. That equation is

... (x -h)² + (y -k)² = r²

Start by completing the square for both x-terms and y-terms.

... x² - 4x + y² + 4y = k

To do that, add the squares of half the coefficients of the x- and y-terms.

... x² - 4x + (-2)² + y² + 4y + 2² = k + (-2)² + 2²

... (x -2)² + (y +2)² = k + 8 = r² . . . . . this is now equal to the square of the radius, so we have

... k + 8 = 6² = 36

Subtracting 8 gives

... k = 28 . . . . . . . matches selection D)

Find the inequality represented by the graph.
baherus [9]

Answer:

y > 1/3 x - 3

Step-by-step explanation:

First, it would be easiest to find the equation of the line from the two integer points given, which are (0, -3) and (3, -2).

Find the change of y over the change of x to get the slope of the line.

(-2 - (-3))/(3 - 0) = 1/3

Since the line intercepts the y axis at (0, -3), the equation of the line would be

y = 1/3x - 3

We can see that the shaded portion is above the line, (and that the line is dotted) so this graph represents

<u>y > 1/3 x - 3</u>
