Which of the following expressions shows how to rewrite 6-7 the additive inverse and displays the expression correctly on a number line?

Option B:

6 + (–7) = –1

Solution:

6 – 7 = 6 + (–7)

6 – 7 = –1

So, the answer is –1.

To find the 6 – 7 the additive inverse in the given number line:

Option A: 6 + (–7)

From 0 moving 6 numbers to the right and then moving 7 numbers to reverse direction.

But here, moving 1 number to the right, the answer is 7.

It is not correct.

Option B: 6 + (–7)

From 0 moving 6 numbers to the right and then moving 7 numbers to reverse direction, the answer is –1.

It is correct.

Option C: 6 – (–7)

From 0 moving 6 numbers to the right and then moving 7 numbers to reverse direction.

But here, moving 13 number to the left, the answer is –7.

It is not correct.

Option D: 6 – (–7)

From 0 moving 6 numbers to the right and then moving 7 numbers to reverse direction.

But here, moving 5 number to the left, the answer is 1.

It is not correct.

Therefore, 6 + (–7) = –1

Hence Option B is the correct answer.

depending on others is critical to survival. my source is apex!

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
