What is the soultion of - 21 = n - 8 what is n

1 answer:

8 0

This is a simple equation:)
We have to isolate "n" to be alone.
-21 = n - 8

First add 8 to both sides.
-21 = n - 8
+8 = + 8 it cancels out on the right side of the equal side and you solve on the left side

soooo
-21 + 8 = -13
-13 = n

Finally our answer is
-13 = n

When in doubt, eat a pineapple:)

Identify the center and the radius of each.<br><br> x^+y^+26x-22y+281=0

Answer:

Center (-13,11) , radius 3

Step-by-step explanation:

The given circle has equation

$x^2+y^2+26x-22y+281=0$

We compare this to the general equation.

$x^2+y^2+2ax+2by+c=0$

where (-a,-b) is the center.

This implies that;

2a=26

$\Rightarrow a=13$

2b=-22

b=-11

The center is therefore (-13,11)

The radius is given by

$r=\sqrt{a^2+b^2-c}$

$r=\sqrt{13^2+(-11)^2-281}$

$r=\sqrt{9}$

The radius is 3
