ololo11 [35]

Answer: Invasions by Barbarian tribes

The most straightforward theory for Western Rome's collapse pins the fall on a string of military losses sustained against outside forces. Rome had tangled with Germanic tribes for centuries, but by the 300s “barbarian” groups like the Goths had encroached beyond the Empire's borders

F(x) = 4x+3x<br> g(x) = 2x-5<br> 7. Find (f+9) (x) <br> 8. Find (f - g) (x)
notka56 [123]

Answer:

7. (f+g)(x) = 6x - 2

8. (f-g)(x) = 2x + 8

Step-by-step explanation:

We are given two function, f(x) and g(x).

We want to find their addition and their subtraction, and we do this combining like terms.

The functions are:

f(x) = 4x + 3

g(x) = 2x - 5

7. Find (f+9) (x)

4x + 3 + 2x - 5 = 4x + 2x + 3 - 5 = 6x - 2

So

(f+g)(x) = 6x - 2

8. Find (f - g) (x)

4x + 3 - (2x - 5) = 4x + 3 - 2x + 5 = 4x - 2x + 3 + 5 = 2x + 8

So

(f-g)(x) = 2x + 8
