Answer:
(L-a)/d + 1 = n
Step-by-step explanation:
Let's isolate (n-1), and after that isolate n:
1) subtract a from both sides: L - a = (n-1)d
2) Divide both sides by d: (L-a)/d = n-1
3) Add 1 to both sides, to isolate n: (L-a)/d + 1 = n

the 0,2 does beautiful as it comes
Answer:
The expression is 20 - 50/5
Step-by-step explanation:
First we have the quotient of 50 and 5.
This is written as:
50/5
And we know that this is equal to 10, but let's leave it as 50/5 for now.
Now we subtract this FROM 20, then we have the number 20, and we subtract 50/5 from it, this is written as:
20 - 50/5
Now we can also solve this:
20 - 50/5 = 20 - 10 = 10
Answer:
y = 
x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x + 2 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
=
The line crosses the y- axis at (0, 1) ⇒ c = 1 , then
y = x + 1 ← equation of perpendicular line
