Apostage stamp is shaped like a rectangle with a perimeter of 88 millimeters. the length (x) is 10 millimeters less than twice the width (y). the system of equations shown below represents this situation.

x = 2y - 10
2x + 2y = 88

which statement is true?

question 4 options:

the width of the stamp is 1 millimeters

the length of the stamp is 36 millimeters

the width of the stamp is 8 millimeters less than the length.

the length of the stamp is 10 millimeters greater than the width

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
