Which of the following expressions is correct?

masya89 [10]

Answer:

The correct answer is: [A]: " -(-21) = 21 " .

________________________________

Step-by-step explanation:

________________________________

Let us examine the answer choices given.

________________________________

Choice: [A]: " -(-21) = 21 . This is correct;

→ since a "negative value of negative value" is a "positive value" ; as shown in this case. The equal sign holds true, since the

"negative of a "negative value" is equal to the "positive value" of that same "positive value equivalent."

________________________________

Choice: [B]: " -(-21) = -21 . This is incorrect. As explained above:

→ a "negative of negative" is a "positive value" .

This answer choice shows that a "negative of negative"; is a "negative" :

→ which is: INCORRECT.

→ Rule out: "Choice: [B]."

________________________________

Choice: [C]: " -(21) = 21 . This is incorrect. The "negative" value [of a positive integer is not equal to the "equivalent positive value" of that same integer.

→ Rule out: "Choice: [C]."

________________________________

Choice: [D]: " (-21) = 21 "; This is incorrect. In a conceptually similar way as explained above—(for "Answer Choice: [C]" — the "negative value equivalent" of an integer is NOT equal to the "equivalent positive value" [of that same integer.].

→ Rule out: "Choice: [D]."

________________________________

The correct answer is: [A]: " -(-21) = 21 " .

Help me this is hard

Following PEMDAS is crucial to solving these. Please Excuse My Dear Aunt Sally

P - Parenthesis

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

Multiplication/Division and Addition/Subtraction are interchangeable.

Now then, number 1 has the following:

$4-2*409-8*96$

There are no parenthesis or exponents, but there is multiplication, so we will start with multiplying. There are two multiplication expressions in the problem.

$-2 * 409 = -818$

$-8 * 96 = -768$

Since you did that, your answer has been simplified to:

$4-818-768$

Now, all you have to do is combine your like terms. Since every term is alike, you can combine the whole expression.

$4-818-768 = -1582$

So, your final answer would be:

$4-2*409-8*96 = -1582$

Hopefully with this information, you can solve the rest. If you have any questions, let me know.

Is the function represented by the table linear

Bess [88]

Answer:

No, because it does not have a constant rate of change.

Step-by-step explanation:

On the <em>x</em><em> </em>side of the table, there is a constant rate of change (+1). However, on the y side, it is not. The first change is +7, the next +5, and the last +6. The rate of change has to be constant on both sides for the table to be considered linear.

A game is played with a deck of 50 cards numbered from 1 to 50. At the end of each round, players calculate their score by addin

liberstina [14]

Answer:

28

Step-by-step explanation:

Since the score is the sum of all cards a player has, the way to make it smallest is to use the smallest cards. So the 7 smallest cards are 1, 2, 3, 4, 5, 6 and 7. So you want to add these up. This gets 28
