Our matrix C is the encoder. Let X be our secret message and let B be our encoded message. Therefore the relationship between the 3 can be represented as:
CX = B
So we want to solve for X (our secret message). So using matrix algebra:
X = C^-1*B
where C^-1 is the inverse of C.
C^-1 = | 3 -2 |
|4 -3 |
So we take C^-1 and multiply it by matrix B to get X. Matrix B is already given to us. So just multiply those two. I used a calculator to get:
X = | 20 8 5 3 15 12 15 |
| 18 9 19 2 12 21 5 |
And since A = 1, B = 2, C = 3, etc....
We decode our message and it says:
X = | T H E C O L O |
| R I S B L U E |
So the answer is: The color is blue (D)
Answer:
its -1 and 3/4
Step-by-step explanation:
because u have to find a common denominator first and then a negative plus a positive is a negative so i hope this helps i just learned this like two weeks ago
Answer:
-3
Step-by-step explanation:
The wording is basically saying the y-intercept so when it talks about initial value thats what its talking about. Its negative because it's on the further down side of the y axis. Y-intercept is where the line of a graph crosses the y axis like shown in the picture it is at -3.
