Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Question
![The image shows two matrices, \( A \) and \( C \), and an expression involving them.
Matrix \( A \) is defined as:
\[
A = \begin{bmatrix} 0 & -2 \\ 2 & 0 \\ 2 & 1 \end{bmatrix}
\]
Matrix \( C \) is defined as:
\[
C = \begin{bmatrix} 1 & -1 \\ 1 & 1 \\ -1 & -1 \end{bmatrix}
\]
The expression to compute is \( 4A + 0.5C \).
Below this expression, there is a blank matrix with spots for six numbers organized in three rows and two columns. Each position in this matrix seems to be indicated with an arrow, signifying calculations to fill in the values after computing the expression \( 4A + 0.5C \).
The task involves multiplying matrix \( A \) by 4, matrix \( C \) by 0.5, and then adding the resulting matrices together. The resulting matrix should be placed in the six unfilled positions in the provided blank matrix.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2d890e9c-fe88-4cd1-bfab-a11ce990423c%2Fbe71586a-13be-4e70-b8ce-959f5c5fe37c%2Foivypj9_processed.png&w=3840&q=75)
