Answer:

Step-by-step explanation:
Given

(a): Write as additive inverse.
An additive inverse is of the form a + (-b)
In this case:


So, the expression can be represented as:

(b): Number line representation
When the expression in (a) is solved.
The result is:

This means that the number line must accommodate 7 and -1.
Having said that, options (b) and (c) are out because their range is 0 to 15 and this excludes -1.
Option (d) is a wrong representation of 
Hence, (a) is correct
Answer:
30 people own a cat
Step-by-step explanation:
Choices:
–8 – 3i
–8 + 3i
8 – 3i
<span>8 + 3i
The additive inverse of the complex number a + bi is -(a+bi) = -a - bi
In this case, a = -8 and b = 3i
a + bi = -8 + 3i
additive inverse is: -(-8+3i) = +8 - 3i
The additive inverse of the complex number -8 + 3i is 8 - 3i. The 3rd choice.

Yes, i believe so because u can count back twice and u will get 5. You could al so do: 7-2=5. Hope this helps
