Answer: and Step-by-step explanation: The matrix L is of form 2x3, in which therentwo rows, representing Costa Rica and Honduras, respectively, and 3 columns, representing pair of shorts, tee shirt and cap, respectively:
L = ![\left[\begin{array}{ccc}0.6&0.3&0.45\\0.9&0.2&0.5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D0.6%260.3%260.45%5C%5C0.9%260.2%260.5%5Cend%7Barray%7D%5Cright%5D)
The matrix M is also a matrix of form 2x3:
M = ![\left[\begin{array}{ccc}1.6&0.85&1.15\\1.5&0.8&1.1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1.6%260.85%261.15%5C%5C1.5%260.8%261.1%5Cend%7Barray%7D%5Cright%5D)
Matrix C is the total cost of both countries, then:
C = L + M
C =
+ ![\left[\begin{array}{ccc}1.6&0.85&1.15\\1.5&0.8&1.1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1.6%260.85%261.15%5C%5C1.5%260.8%261.1%5Cend%7Barray%7D%5Cright%5D)
To add 2 matrices, you have to add the first term of the first matrix to the first term of the second matrix and so on:
C = ![\left[\begin{array}{ccc}0.6+1.6&0.3+0.85&0.45+1.15\\0.9+1.5&0.2+0.8&0.5+1.1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D0.6%2B1.6%260.3%2B0.85%260.45%2B1.15%5C%5C0.9%2B1.5%260.2%2B0.8%260.5%2B1.1%5Cend%7Barray%7D%5Cright%5D)
C = ![\left[\begin{array}{ccc}1.6&1.15&1.6\\2.4&1&1.6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1.6%261.15%261.6%5C%5C2.4%261%261.6%5Cend%7Barray%7D%5Cright%5D)
The total cost for the products in each country is
C = ![\left[\begin{array}{ccc}1.6&1.15&1.6\\2.4&1&1.6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1.6%261.15%261.6%5C%5C2.4%261%261.6%5Cend%7Barray%7D%5Cright%5D)

Step-by-step explanation:
The inverse of a function maps the domain onto the range.
<span>the slope of this line is </span>zero slope
Answer:
какие?
Step-by-step explanation:
Answer:Add the equations. 3y and -3y will cancel.
Step-by-step explanation:
Then you are left with 9x =18. Solve for x by dividing both sides by 9 to get x=2. Substitute 2 in place of x in either of the original equations to solve for y.
