Your answer is B, "The function g because the graphs of f and g are symmetrical about the line y=x"
I believe it's C) 60 because ideally it would be 3 for every 25, 20 x 25 = 200, so then you would do 3 x 20 = 60
Answer:
A) arithmetic sequence
g(n) = 20 + 3n
Step-by-step explanation:
Each minute, the number of pages increases by 3, which means the common difference is 3 (because it is being added, not multiplied).
If there is a common difference, it's an arithmetic sequence. (Geometric sequences have common ratios.)
If she starts at 20 pages, then you just need to multiply 3 by the number of minutes passed (n) and add it to 20 to find the page she's on.
- 2.1 = y/6 + 17.1
- 2.1 - 17.1 = y/6
- 19.2 = y/6
19.2*6 = y
-115.2 = y
So y = - 115.2.
Hope this helps ! This "/" is a fraction.
