an equation for the line in point-slope form and general form is :
y = ax+b a : slope ; the Passing through (x' ; y')
y' = ax'+b
y-y' =a(x-x') and : x' =-5 y' =6
calculate a :
let : y = ax+b .....(D)
....y=7x-1....(D')
.(D) perpendicular to(D') : slope (D) × slope (D') = -1

slope (D') = 7
slop(D)×(7 = -1
slope (D) = -1/7
equation for the line : y-y' =a(x-x')
y-6 =(-1/7) (x+5)

Maureen, Frank, Tashia, Zane, Eric, and Wesley are addressing envelopes for volunteer work at a local charity. They were given ¾

jolli1 [7]

Answer:

The fraction of the entire mail each person address = 1/8

Step-by-step explanation:

Given that:

number of people addressing envelopes = 6

If they gave out 3/4 of an entire mailing address.

Then, the amount of mailing not addressed is:

= 1 - 3/4

= $\dfrac{4-3}{4}$

= 1/4

If 6 people shared 3/4 of an entire mailing to address evenly.

Then: each person gets:

$=\dfrac{3}{4} \div 6$

$=\dfrac{3}{4} \times \dfrac{1}{ 6}$

= 1/8

The fraction of the entire mail each person address = 1/8
