The answer is: x = 10, y = 2

Leave a thanks because your welcome :)

Work:

x + y = 12
(10) + (2)+  = 12
Correct

x - 2y = 6
(10) - 2(2) = 6
10 - 4 = 6
Correct

To create an entry code, you must first choose 2 letters and then 2 single digit numbers. How many entry codes can you create?
ivann1987 [24]

Answer:

55600

Step-by-step explanation:

First times the number of possibilities of the amount of letters it could be so 26X26 as it is a non consecutive possibility that means both letters have the possibility to be the same. Then take the product of 26X26 and multiply it by the possibilities of the first number which is 10 then repeat that by again multiplying the product by 10 to represent the number of possibilities for the second number

Start with the basic function f(x)=2x. If you have an initial value of 1, then you end up with the following iterations. f(1)=2*
denpristay [2]
<span>f(x)=2x

f(1)=2*1=2

f^2(1)=2*2*1=4

f^3(1) =2*2*2*1=8

1. If you continue this pattern, what do you expect would happen to the numbers as the number of iterations grows?

I expect the numbers continue growing multiplying each time by 2.

Check your result by conducting at least 10 iterations.

f^4(1) = f^3(1) * f(1) = 8*2 = 16

f^(5)(1) = f^4(1) * f(1) = 16 * 2 = 32

f^6 (1) = f^5 (1) * f(1) = 32 * 2 = 64

f^7 (1) = f^6 (1) * f(1) = 64 * 2 = 128

f^8 (1) = f^7 (1) * f(1) = 128 * 2 = 256

f^9 (1) = f^8 (1) * f(1) = 256 * 2 = 512

f^10 (1) = f^9 (1) * f(1) = 512 * 2 = 1024

2. Repeat the process with an initial value of −1. What happens as the number of iterations grows?

f(-1) = 2(-1) = - 2

f^2 (-1) = f(-1) * f(-1) = - 2 * - 2 = 4

f^3 (-1) = f^2 (-1) * f(-1) = 4 * (-2) = - 8

f^4 (-1) = f^3 (-1) * f(-1) = - 8 * (-2) = 16

f^5 (-1) = f^4 (-1) * f(-1) = 16 * (-2) = - 32

As you see the magnitude of the number increases, being multiplied by 2 each time, and the sign is aleternated, negative positive negative positive ...

How can you understand porportions
BlackZzzverrR [31]

A proportion is a statement that two ratios are equal.  A ratio is a comparison of two different quantities.  "Miles per hour" is a ratio.  "Dollars per pound" is a ratio.  A proportion is that two of these things are equal.

For example, paying $2/pound for apples is the same as paying $6 for 3 pounds:

   \dfrac{\$2}{1 \text{ pound}} = \dfrac{\$6}{3 \text{ pounds}}

That's a portion.

When working with proportions in word problems, you start by setting up one ratio/fraction where you know all the information.  You then set up the second one that's missing a piece of information, but you make sure to set it up using the same structure.

If your first ratio is "miles over hours," then the next ratio has to have the same organization.

If your first ratio is "rise over run," then the next ratio has to have the same organization.
