what grid ⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀
Answer: f(f(f(x)))=8x-7
Step-by-step explanation:
Since we were given f(x) and f(f(x)), We plug that into f(x) again to get f(f(f(x))).
2(4x-3)-1 [distribute]
8x-6-1 [combine like terms]
8x-7
Ab - c = 9 |subtract ab from both sides
- c = 9 - ab |change signs
c = -9 + ab
c = ab - 9
The correct answer is A because 1000 m is 1 km
Hope this helped :)
