Did you finish the Precal test yet? If you did, may you be so kind as to let me know of the answers? I am so desperate and I saw your questions as a sign of help.
A property of inverse functions is that if f(x) = a, g(a) = x F(x) = (5x+1)/x G(x) = x/(5x+1) Plug in x = 3. F(3) = 16/3 G(16/3) = 16/83. Since it doesn’t equal 3, it’s not an inverse function

The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the ordered pair for the center.
(x - (- 3))² + (y - 6)² = 10²
(x + 3)² + (y - 6) = 100
(f + g)(x) = f(x) + g(x)
(f + g)(x) = 3x + 5 + x^2 = x^2 + 3x + 5
Answer: Choice D
Answer:
c
Step-by-step explanation:
i just took the test
The answer is 95% because 19/20 equals 0.95 and 0.95*100 equals 95%
2798 divided by 20 equals 139.9
