JulsSmile [24]3 years ago

Answer:

Step-by-step explanation:

Given (x - 2)^2 + (y + 3)^2 = 9, compare this to the standard equation of a circle, (x - h)^2 + (y - k)^2 = r^2.

It then becomes obvious that h = 2 and k = -3; the coordinates of the center of the circle are (2, -3).

If r^2 = 9, then r must be 3.  This is the radius of the circle.

To draw this circle:  Plot the center (2, -3).  Take a compass and open it up so that the distance between the compass points is 3, representing the radius of the circle.  Now use the compass to draw a circle with radius 3 and center at (2, -3).

How do you find endpoints of a line segment with a given endpoint and midpoint?
seraphim [82]

In order to find the second endpoint or a line segment given the first and the midpoint, you need to realize that the midpoint is an average of the two endpoints. Given that fact, we can derive this formula looking at x values of points A and B with midpoint M. Remember this is only looking at the x values.

(A + B)/2 = M

So if we are looking for A, we can solve for A and use this modified formula.

(A + B)/2 = M

A + B = 2M

A = 2M - B

Now we can do this with the y values of these points as well. We then have the coordinates of both parts of A.

6 16x + 5y = -2<br> 4x - y=-2
Grace [21]

Answer:

x=2/9,y=26/9

Step-by-step explanation:

This is a simultaneous equation

16x+5y=-2..(1)

4x-y=-2...(2)

From (2) make y the subject of formula

y=4x+2..(3)

Substitute (3) into (1)

16x+5(4x+2)=-2

16x+20x+10=-2

36x-10=-2

Add 10 to both sides

36x=8

Divide both sides by 36

x=8/36

Divide both denominator and numerator by 4

x=2/9

Substitute the value x into (3)

y=4(2/9)+2

y=8/9+2

Let the LCM be 9

y=8+18/9

y=26/9

Therefore x=2/9,y=26/9
