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:)

Geometry question plz help me!
denis23 [38]

Answer:

Step-by-step explanation:

Any linear equation can be written as y = mx + b

The point will determine b

The slope (m) is found by this formula for a perpendicular line

m1 * m2 = - 1

m1 = -1/m2

m1 = -1/(-2/3)

m1 = 3/2

So our equation looks like

y = 3/2 x + b

Now we use the point (4,-8)

-8 = 3/2 (4) + b

-8 = 3(2) + b

-8 = 6 + b

b = - 14

The answer is

y = 4/2 - 14
