Question

-6,7 -(-7,6)=-5,4-6,8=​

Answer 1

-6,7-(-7,6) = -6,7+7,6 = 0,9

-5,4-6,8 = -(5,4+6,8) = -12,2

Answer 2

Ответ:

$-6.7-(-7.6)=-6.7+7.6=0.9\\-5.4-6.8=-12.2$

Answer 3

It looks like you're performing some calculations with ordered pairs (coordinates). Let's break down each step:

1. -6,7 - (-7,6): When you subtract a negative value, it's the same as adding the positive value. So, the calculation becomes: -6,7 + 7,6 = ( -6 + 7 , 7 + 6 ) = ( 1 , 13 )

2. -5,4 - 6,8: Subtraction of two coordinates is done by subtracting their respective components: -5 - 6 = -11 4 - 8 = -4 So, -5,4 - 6,8 = ( -11 , -4 )

Putting it all together:

-6,7 - (-7,6) = (1, 13) -5,4 - 6,8 = (-11, -4)

I've broken down each step of the calculation, so if you have any specific questions about the process or the result, feel free to ask!
