Answer:

Step-by-step explanation:

(g•f)(2) = g(f(2))

Since f(x) = 5x - 4

f(2) = 5(2) - 4 = 10 - 4 = 6

(g•f)(2) = g(f(2))

g(f(2)) = g(6) = (6)^2 = 36

Step-by-step explanation:

  • set F function in g function:

gof(x) = (5x-4)2

  • simplified:

gof(x) = 10x-8

  • put 2 in function

gof(2) = 10(2) - 8 => 20-8 => 12

Pamela and Debbie are shelving books at a public library. Pamela shelves 26 books at a time, whereas Debbie shelves 7 at a time.
Ira Lisetskai [31]

If both Pamela and Debbie can shelf the same number of books at the end, the smallest number of books each could have shelved is 182

The number of books that Pamela can shelf at a time = 26

The number of books that Debbie can shelf at a time = 7

If both Pamela and Debbie can shelf the same number of books at the end, the smallest number of books each could have shelved is the least common multiple of 26 and 7

The Least common multiple of 26 and 7  = 182

Therefore, if both Pamela and Debbie can shelf the same number of books at the end, the smallest number of books each could have shelved is 182
