1. (3 x 5) + (6 x 5) = (16 x 5) – (________ x 5) <br> 2. (3 x 8) + ( ________ x 8) = 13 x 8

Tcecarenko [31]

1. x3+x5=16. Multiply each side by 3: x+3x5=48. Continue simplifying and solving: 5x5+3x5=48. 8x5=48. 8x=240. x=30.

2. –7 x 8. –60. 3 ... You need to read the problem and know what information you (3 x 5) + (6 x 5) = (16 x 5) – (________ x 5(3 x 8) + ( ________ x 8) = 13 x 8

Find the inverse of the matrices if they Exist. Use the algorithm introduced in the section. [1 0 -2 -3 1 4 2 -3 4]

KiRa [710]

Answer:

\frac{1}{2} \left[\begin{array}{ccc}16&6&2\\20&8&2\\7&3&1\end{array}\right]

Step-by-step explanation:

Given is a matrix 3x3 as

$\left[\begin{array}{ccc}1&0&2\\-3&1&4\\2&-3&4\end{array}\right]$

|A| =2 hence inverse exists.

Cofactors are 16 20 7

6 8 3

2 2 1

Hence inverse =

$\frac{1}{2} \left[\begin{array}{ccc}16&6&2\\20&8&2\\7&3&1\end{array}\right]$
