Find the coordinate of the midpoint of the segment with the given endpoints -7 and 8
Pachacha [2.7K]

Answer:

<em>The coordinate of the midpoint is 1/2</em>

Step-by-step explanation:

<u>Midpoint</u>

The midpoint of a segment defined in a one-dimension system is

\displaystyle \bar x=\frac{x_1+x_2}{2}

Where x1 and x2 are the coordinates of the points.

The given segment has endpoints x1=-7 and x2=8, thus:

\displaystyle \bar x=\frac{-7+8}{2}

\displaystyle \bar x=\frac{1}{2}

The coordinate of the midpoint is 1/2

I just don't know what to do for this at all.
True [87]

Answer:

40 degrees

A supplementary angle is when two angles add up to equal 180 degrees. So to figure out that one it would be 180-140=40. The other angle is 40 degrees.

Find the coordinates of the circle and the radius y²+2x+x²-24y= -120
riadik2000 [5.3K]
We know that
the equation of a circle is
(x-h+(y-k)²=r²
where (k,k)----> is the center
and
r----> is the radius
y²+2x+x²-24y= -120

Group terms that contain the same variable
 (y²-24y)+(x²+2x)=-120

Complete the square twice. Remember to balance the equation by adding the same constants to each side
 (y²-24y+144)+(x²+2x+1)=-120+144+1

<span>Rewrite as perfect squares</span>

(y-12)²+(x+1)²=25

(x+1)²+(y-12)²=5²

the answer is
the coordinates of the center are (-1,12)
the radius is 5 units
