Maya is asked to find the GCF of each term in the expression 32xy- 18y. Her work is shown below.
Factors of 32xy: 1, 2, 4, 8, 16, 32, X, y
Factors of 18y: 1, 2, 3, 6, 9, 18, y
GCF: (1)(2)(x))
The GCF is 2xy.
Which best describes the accuracy of Maya's solution?
Maya's solution is accurate.
Maya factored 32xy incorrectly.
Maya factored 18y incorrectly,
Maya factored correctly, but did not find the correct GCF.

If p(x) is the total value of the production when there are x workers in a plant, then the average productivity of the workforce at the plant is a(x) = p(x) x . (a) find a'(x). a'(x) = xp'(x) − p(x) x a'(x) = xp'(x) − p(x) x2 a'(x) = p'(x) − p(x) x a'(x) = xp'(x) − p'(x) x2 a'(x) = p'(x) − xp(x) x2 why does the company want to hire more workers if a'(x) > 0? a'(x) > 0 ⇒ a(x) is ; that is, the average productivity as the size of the workforce increases. (b) if p'(x) is greater than the average productivity, which of the following must be true? p'(x) − xp(x) > 0 p'(x) − xp(x) < 0 xp'(x) − p'(x) > 0 xp'(x) − p(x) < 0 xp'(x) − p(x) > 0
