A. 3n + 4
First Four Terms: 7, 10, 13, 16
Tenth Term: 34:
Plug in 10, 3 x 10 = 30 + 4 = 34
B. 4n - 5
First Four Terms: -1, 3, 7, 11
Tenth Term: 35
Plug in 10, 4 x 10 = 40 - 5 = 35
Answer:
![7 + (-8)](https://tex.z-dn.net/?f=7%20%2B%20%28-8%29)
Step-by-step explanation:
Given
![7 - 8](https://tex.z-dn.net/?f=7%20-%208)
(a): Write as additive inverse.
An additive inverse is of the form a + (-b)
In this case:
![a = 7](https://tex.z-dn.net/?f=a%20%3D%207)
![b = -8](https://tex.z-dn.net/?f=b%20%3D%20-8)
So, the expression can be represented as:
![7 + (-8)](https://tex.z-dn.net/?f=7%20%2B%20%28-8%29)
(b): Number line representation
When the expression in (a) is solved.
The result is:
![7 - 8 = 7 + (-8) = -1](https://tex.z-dn.net/?f=7%20-%208%20%3D%207%20%2B%20%28-8%29%20%3D%20-1)
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 ![7 - 8](https://tex.z-dn.net/?f=7%20-%208)
Hence, (a) is correct
