Answer:

A. 3

Step-by-step explanation:

Hello

X^2 + 8X + (8/2)^2 + Y^2 + 14Y + (14/2)^2 = (8/2)^2 + (14/2)^2-56

(X+4)^2 + (Y+7)^2 = 16 + 49 - 56

(X+4)^2 + (Y+7)^2 = 9

Then

The radius for that circle is 3

Best regards

Why is the number 6 scared of the number 7?
Lady_Fox [76]
This is a well known joke:

Why six afraid of seven? Because seven ate nine!

It is supposed to be a "word game" where instead of writing eight, the authour wrote ate, which sound the same but means something different.


Hope it helped,

Happy homework/ study/ exam!

What is an equation of the line that passes through the points <br> (8,2) and <br> (7,1)?
gogolik [260]

Answer:

Step-by-step explanation:

first, we find the slope

slope = (y2 - y1) / (x2 - x1)

(8,2)....x1 = 8 and y1 = 2

(7,1)....x2 = 7 and y2 = 1

now we sub

slope = (1 - 2) / (7 - 8) = -1/-1 = 1

y = mx + b

slope(m) = 1

use either of ur points...I will use (8,2)...x = 8 and y = 2

now we sub and find b, the y intercept

2 = 1(8) + b

2 = 8 + b

2 - 8 = b

-6 = b

so ur equation is : y = 1x - 6....or just y = x - 6 <===
