Answer:

2(x-3) = 8

Step-by-step explanation:

first it says 'difference of a number and 3' so that equals to (x-3), we use 'x' for the variable for the unknown number

next it says 'twice', so two times which equals 2(x-3)

last it says 'is 8', which means 'equals' so "2(x-3) = 8"

What equation do I need to use?

To ease your problem, consider "L" as you x-axis
Then the coordinate become:
A(- 4 , 3)   and B(1 , 2) [you notice that just the y's changed]

This is a reflection problem.
Reflect point B across the river line "L" to get B', symmetric of B about L.
The coordinates of B'(1 , -1) [remember L is our new x-axis]
JOIN A to B' . AB' intersect L, say in H
We have to find the shortest way such  that AH + HB = shortest.
But HB = HB' (symmetry about L) , then I can write instead of 
AH + HB →→ AH + HB'. This is the shortest since the shortest distance between 2 points is the straight line and H is the point requiered

For the purpose of determining the value of its end-of-year inventory, a clothing store creates a list at the end of the year of
weeeeeb [17]

Answer:

e. A census, because the wholesale prices of all items are listed.

Step-by-step explanation:

A census encompasses collecting data of an entire population as well evaluation of the characteristics of an entire population. Every item currently in store alongside their wholesale price was included in the survey here. None was excluded. So we cannot call the activity a sample survey. Since all items were counted, the best description to give to this activity is "a census".
