Mathematics

Answer:

<em>(D). (8, - 5) </em>

Step-by-step explanation:

Coordinates of a center of a circle (x - h)² + (y - k)² = r² is (h, k)

Coordinates of the midpoint are ( \frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )

(x² - 10x + 25) + (y² + 2y + 1) = 25

(x - 5)² + (y + 1)² = 5²

(5, - 1) are coordinates of the center of the circle and (5, - 1) is a midpoint of the segment connected (2, 3) and (x, y)

5 = (2 + x) / 2 ⇒ x = 8

- 1 = (3 + y) / 2 ⇒ y = - 5

<em>(D). (8, - 5)</em>

First find midpoint:  \left( \frac{-1+5}{2}, \frac{6+5}{2}\right) = (2, 5.5) 

Find slope of line that passes through R and S:    slope = \frac{6-5}{-1-5} = \frac{-1}{6}   

Negative reciprocal of slope to get slope of perpendicular:    new slope = 6

Line will be:  y-5.5=6(x-2) 

  y = 6x - 6.5

Suppose you deposited ​$100 in a savings account 3 years ago. The simple interest rate is 3.2 %. The interest that you earned in
astraxan [27]
It's not compounded interest, you just get $3.20 every year.
$100 * 0.032 = $3.20
$3.20 * 3 years = $9.60

1 7/11 divided 2 1/2 <br> Show work if you can :)
Dmitry_Shevchenko [17]
You can say 1 and 7/11 is 18/11 and 2 and 1/2 is 5/2 so : 
18/11 ÷ 5/2  so 18/11 * 2/5 = 36/55 = 0.654 :)))
i hope this is helpful 
have a nice day

Which equation represents the line that passes through (-6,7) and (-3,6)
astraxan [27]

Answer:

x+3y=15

Step-by-step explanation:

<h2>Formula :- the equation of line which passes through the two points (x1,y1) and (x2,y2)</h2><h2>T-y1/y1-y2=x-x1/x1-x2[/tex]</h2>

therefore, the equation of the line which passes through the two points (-6,7) and (-3,6) is

y1=7,y2=6

x1=-6 ,x2=-3

by using above formula

y-7/7-6=x+6/-6+3

y-7=x+6/-3

by cross multiply

-3y+21=x+6

x+3y=21-6

x+3y=15

hence, this is required of line that passes through (-6,7) and (-3,6).
