Step-by-step explanation:
given f(x) = 2/x and g(x) = 2/x
f(g(x)) = 2/(g(x)) = 2/2/x = x/2 × 2 = x
g(f(x)) = 2/(f(x)) = 2/2/x = x/2 × 2 = x
therefore they are inverses
since f(g(x)) = g(f(x)) = x.
Answer:
3 + 9
Step-by-step explanation:
Distribute the 3 to both numbers, so 3 x 1 = 3, and 3 x 3 = 9.
5x=38-3
5x=35
x=7 good luck

Divide 7.8 by 1.18:
7.8 / 1.18 = 6.61 = 6.6 rounded to the nearest tenth.
When you divide scientific notation, subtract the exponents: 20 - 13 =7
The answer becomes 6.6 x 10^7
