f(x) =
g(x) = 
g⁻¹(x): x = 
x(y + 4) = 5y - 1 <em>multiplied both sides by y + 4</em>
xy + 4x = 5y - 1 <em>distributed x into y + 4 on left side</em>
xy + 4x + 1 = 5y <em>added 1 to both sides</em>
4x + 1 = 5y - xy <em>subtracted xy from both sides</em>
4x + 1 = y(5 - x) <em>factored y on the right side</em>
= y <em>divided 5 - x from both sides</em>
f(x) ≠ g⁻¹(x) so they are not inverses of each other
Answer: NOT INVERSES because f(x) ≠ g⁻¹(x)
Answer:
To divide a decimal number by a decimal number, multiply the divisor by as many tens as necessary until we get a whole number, and remember to multiply the dividend by the same number of tens. For example, 13.8 ÷ 0.6 becomes 138 ÷ 6 = 23.
Answer: 417,600,000,000,000
Step-by-step explanation: 2.9(10)^5(7.2)(10^2)/5(10^-8)
(2.9)(100,000)(7.2)(10^2)/5(10^-8)
(290,000)(7.2)(10^2)/5(10^-8)
2,088,000(10^2)/5(10^-8)
(2,088,000)(100)/5(10^-8)
208,800,000/5(10^-8)
208,800,000/5(1/100,000,000)
208,800,000/1/20,000,000
417,600,000,000,000
