Answer:
A
Step-by-step explanation:
The rule is, whenever you plug in g(x) into f(x) or vice versa, they always must equal x. So if you plugged in g(x) into f(x), then the outcome should be <em>x</em>. If the output is not x, then they are not inverses.
Answer:
No
Step-by-step explanation:
The sum of the smaller sides is not bigger than the largest side, 122. ( 31 + 89 = 120 < 122)
Answer:
3.5 meters
Step-by-step explanation:
- 1:4 = x:14 ; where x is the unknown length of A
- 1/4 = x/14 (Cross multiply)
- Giving us, 4×x = 14×1
- 4x = 14 (Divide both sides by co-efficient of x, which is 4)
- x = 14/4
- x = 3.5
- Therefore, the length of A is 3.5 meters.
