Answer:

105.876373581

Step-by-step explanation:

8.563 + 4.8292 = 13.3922

13.3922 × 9.183 = 122.9805726

122.9805726 ÷ 1.192 = 103.171621309

103.171621309 ÷ 1.192 = 86.5533735811

86.5533735811 + 19.323 = 105.876373581

4x+2y=-24 -4x+y = 12

allsm [11]

Answer:

Step-by-step explanation:

4x+2y = -24 -------------(i)

-4x+y = 12 -------------(ii)

add (i) &(ii) 3y = -12

y = -12/3

y = -4

Put y = (-4) in (i)

4x + 2*(-4) = -24

4x - 8 = -24

4x = -24 + 8

4x = -16

x = -16/4

x = -4

What is the product?

kobusy [5.1K]

Answer:

$\begin{bmatrix}7\\ 4\\ 2\end{bmatrix}$

Step-by-step explanation:

We have the product, $\begin{bmatrix} 3& 6& 1\\ 2& 4& 0\\ 0& 6& 2\end{bmatrix}\times \begin{bmatrix}2\\ 0\\ 1\end{bmatrix}$ .

As, we have the product of a 3×3 and 3×1 matrix, the resultant matrix will be of order 3×1.

So, we get,

$\begin{bmatrix} 3& 6& 1\\ 2& 4& 0\\ 0&6&2\end{bmatrix}\times \begin{bmatrix}2\\ 0\\ 1\end{bmatrix}$

⇒ $\begin{bmatrix}3\times 2+6\times 0+1\times 1\\ 2\times 2+4\times 0+0\times 1\\ 0\times 2+6\times 0+2\times 1\end{bmatrix}$

⇒ $\begin{bmatrix}7\\ 4\\ 2\end{bmatrix}$ .

Thus, the resulting product is $\begin{bmatrix}7\\ 4\\ 2\end{bmatrix}$ .
