Answer:

B) $\displaystyle x ≤ 0$

Step-by-step explanation:

2(x + 12) − 16 ≤ 8

$\displaystyle \frac{2(x + 12)}{2} ≤ \frac{24}{2} \\ \\ x + 12 ≤ 12 \\ \\ x ≤ 0$

What is the element a^23 in matrix A? <br> A=8 -4 -3<br> 3 -9 -5<br> -8 8 8

labwork [276]

8 -4 -3
3 -9 -5-8 8 8

This is a matrix of 3 rows and 3 columns (it's called square matrix because the number of rows = the number of columns)

To localise an element of a matrix we use indices R and C, the first index being ALWAYS the row and the second, ALWAYS the column.

Hence:
A₂₃ = the element in row 2 and column 3, that is - 5

COLUMN
1st 2nd 3rd
--------------------------------
1st | 8 -4 -3
ROW 2nd | 3 -9 -5 3rd |-8 8 8

Determine whether these two statements are logically equivalent by constructing truth tables. -(PA-Q) and PvQ After you construc

Lady bird [3.3K]

Answer:

The statement $\neg(p \land \neg q)$ and the statement $\neg p \lor q$ are logically equivalent.

Step-by-step explanation:

You use truth tables to determine how the truth or falsity of a complex statement depends on the truth or falsity of its components.

There are four steps to building a truth table:

Determine the number of different propositions in the statement, for this case two (p and q)
The main operators have to be identified.

For the first statement we have:

$\neg (p \land\neg q)$ two operators and ( $\land$ ) and not ( $\neg$ ).

For the second statement $\neg p \lor q$ we have two operators or ( $\lor$ ) and not ( $\neg$ )

3. Next, the basic input values are assigned to each letter.

4. The final step is to calculate the values of each logical operator.

Following these steps, we can generate the truth table.

Two statements are logically equivalent if, and only if, their resulting forms are logically equivalent when identical statement variables are used to represent component statements.

We can see from the truth table that the statement $\neg(p \land \neg q)$ and $\neg p \lor q$ have the same truth values, so they are logically equivalent.
