Answer: 10 inches
Step-by-step explanation:
We know that each single Denalia shell is 2 inches. So let's calculate how many inches a 25 shell necklace would be
25(number of shells)×2(inches per 1 shell) = 50in
Next let's find the second necklace with 20 shells
20(number of shells) × 2(inches per 1 shell) = 40in
Finally we take the difference between the two
50in - 40in = 10 inches
Thus, the difference between a 25 shell necklace and a 20 shell necklace is 10 inches.

Answer:
To get the function g, shift f up by 3 units and to the right by 9 units.
Step-by-step explanation:
The given functions are
If f(x) is a parent function, then g(x) can be written in the form of f(x) as
...(1)
The translation is defined as
... (2)
Where, a is horizontal shift and b is vertical shift.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
On comparing (1) and (2), we get
It means, to get the function g, shift f up by 3 units and to the right by 9 units.
Ok to start you have to put
2+-1/9 - 4+-1/3
what exactly is the question because without the proper info. nobody is going to be able to figure it out.
Answer: Choice C) -11
-----------------------------------
Explanation:
The first equation given is y = 3 - 1/2x
In other words, y is the same as 3 - 1/2x.
We can replace y in the second equation with 3 - 1/2x
This is known as substitution (think of a substitute teacher who is a temporary replacement for your teacher)
Doing this leads to...
3x+4y = 1
3x+4*y = 1
3x+4*( y ) = 1
3x+4*( 3 - 1/2x ) = 1 <<--- y has been replaced with 3-1/2x
3x+4*(3) +4*(-1/2x) = 1
3x+12-2x = 1
3x-2x+12 = 1
x+12 = 1
x+12-12 = 1-12 <<-- subtracting 12 from both sides
x = -11
Which is why the answer is choice C) -11
