Which of the following is a correct interpretation of the expression -4 - (-7)?

Zielflug [23.3K]

Answer:

Step-by-step explanation:

So we have the expression:

$-4-(-7)$

First, simplify. Two negatives make a positive. Therefore, the -(-7) turns into +7:

$-4-(-7)\\=-4+7$

When adding on the number line, we move to the right.

Therefore, the correct interpretation is the value 7 digits to the <em>right</em> of -4.

D is the correct answer.

Novay_Z [31]

Answer:

5x+8y

2(x+4y)+3x

2x+8y+3x

Now we can combine like terms.

5x+8y.
