Yvette encoded a secret phrase using matrix multiplication. using a = 1, b = 2, c = 3, and so on, she multiplied the clear text code for each letter by the matrix to get a matrix that represents the encoded text. the matrix representing the encoded text is . what is the secret phrase? determine the location of spaces after you decode the text.

Blue is the glove.

Step-by-step explanation:

Assuming the matrix which multiplies the clear text code is:

     |-3   2|

C =|-4   3|

And the matrix re<presenting the encoded text is :

     |10  -26  -49  9  3  -13   -50|

B = |16  -33  -63  16  9  -10  -65|

Calling X the secret message, the relationship between the 3 matrices can be represented as:

C*X = B  

Solving for X:

X = C^-1*B

where C^-1 is the inverse of C.  

         |-3   2|

C^-1 =|-4   3|

Multiplying:

     |2       1221591920 |

X = |8571215225 |

Replacing numbers by its corresponded letter (see picture attached):

     |BL  UEIST |

x = |HEGLOVE |

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

the answer would be  

a.

3: 1
