Some native american tribe made jewelry with dentalia shells.each denalia shell is 2 inches long how much longer would a necklac
solong [7]

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.

F(x)=x^2<br> g(x) = (x– 9)^2 +3<br> We can think of g as a translated (shifted) version of f.
Vinil7 [7]

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

f(x)=x^2

g(x)=(x-9)^2+3

If f(x) is a parent function, then g(x) can be written in the form of f(x) as

g(x)=f(x-9)+3        ...(1)

The translation is defined as

g(x)=f(x+a)2+b       ... (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

a=-9,b=3

It means, to get the function g, shift f up by 3 units and to the right by 9 units.

Given the system of equations, what is the x-coordinate of the solution?
Nimfa-mama [501]
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
