There are many benefits to using folders when working with lots of files. Here are a few examples:
- You can use folders to sort your files by type, almost like drawers in a desk, so you might have folders for Music, Photographs, Documents, etc.
- You can use folders to group files together into a specific group. For example in your Photographs folder you might have a folder titled BirthdayPhotographs for all the photographs from your birthday.
- As in the example above you can nest folders to create sub-categories. Documents might include folders for Homework, Stories, Poems
- Folders can have different permissions applied to them, allowing you to keep personal files in a private folder only you can access, or secret files in a folder that doesn't show up in the normal list of folders!
Answer:
C
Step-by-step explanation:
A function means that a graph cannot have repeating x values, so to test if something is a function we do the horizontal line test. You simply draw a vertical line and if the graph touches it twice it is not a function.
The prime number is 17 if you look at a multiplication chart there is nothing that equals 17 on there right ?? Even if you divide you will have to find something close to 17 like 16
Answer:
Step-by-step explanation:
Given equation of the quadratic function is,
y = x² + 5x - 7
Convert this equation into vertex form,
y = x² + 2(2.5x) - 7
= x² + 2(2.5x) + (2.5)² - (2.5)² - 7
= (x + 2.5)²- 6.25 - 7
= (x + 2.5)² - 13.25
Therefore, vertex of the function is → (-2.5, -13.25)
For the solutions,
y = 0
(x + 2.5)² - 13.25 = 0
x = (±√13.25) - 2.5
x = (±3.64) - 2.5
x = 1.14, -6.14
Solutions → (-6.14, 0) and (1.14, 0)
Answer:
y = x/4 -1/2
Step-by-step explanation:
given coordinates : ( -2, -1 ) and ( 2 , 0 )
gradient = y2 - y1 / x2 - x1
= 0 - -1 / 2 - -2
= 1/4
equation of line:
y - y1 = m( x - x1 )
y - 0 = 1/4 ( x - 2 )
y = x/4 -1/2
the line shown below to confirm:
