Calculate the value for each determinant:

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

$\begin{vmatrix}3 & -1\\ -3 & 4\end{vmatrix}=(3\times 4)-(-1)\times (-3)$

= 12 - 3

= 9

$\begin{vmatrix}8 & -1\\ -4 & -1\end{vmatrix}=8\times(-1)-(-1)\times(-4)$

= -8 - 4

= -12

$\begin{vmatrix}-12 & -1\\ 12 & 5\end{vmatrix}=(-12)\times(5)-(-1)\times(12)$

= -60 + 12

= -48

$\begin{vmatrix}2 & -1\\ 2 & -1\end{vmatrix}=2\times(-1)-(2)\times(-1)$

= -2 + 2

= 0

$\begin{vmatrix}0 & -1\\ 17 & 4\end{vmatrix}=0\times(4)-(-1)\times(17)$

= 17

$\begin{vmatrix}1 & 0\\ 0 & 1\end{vmatrix}=1\times(1)-(0)\times(0)$

= 1

6+8x-9=11x+14-3x, can this equation be always, sometimes, or never true.

goblinko [34]

To answer the question above, simplify both sides of the equation. This gives,
8x - 3 = 8x + 14
Next, cancel the term 8x because it appears on both sides of the equation giving,
-3 = 14
That is NOT true. Therefore, the answer is the equation is NEVER TRUE.

Given f(x) and g(x) = k • f(x), use the graph to determine the value of k.

Answer:

I believe it is A -2.... If you see where they are each plotted and multiply them which is 1 and -2 you would get -2.. Hope that helps.
