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

According to the properties of inequality, when should the inequality symbol be reversed when solving a two-step inequality in t

Svetllana [295]

Answer is when a is negative

To solve inequalities, you are trying to get the X variable by itself with a positive charge of 1. If the coefficient in front of it is negative, you must flip the sign in the other direction.

Example:

-3x < 9

divide each side by a negative 3. This means we have to flip the sign.

x > -3
