First, we convert the given initial length of the ribbon by the conversion factors,
1 yd = 3 ft
1 ft = 12 inches
Converting,
(1 yd)(3 ft/ 1 yd)(12 in/1 ft) = 36 in
Since Luann used 33 inches, the length of the unused ribbon is 3 inches.
3/4 = m/32 cross multiply 4m = (32)(3) 4m = 96 m = 96/4 m = 24
Ax + by = c
Ax + by (- Ax) = c (-Ax)
by = c - Ax
by/b = (c - Ax)/b
y = (c - Ax)/b
hope this helps :D
Answer:
Option (c) : f' (x) = - 2 / 5x
Your pay is described by a piecewise function p(t) where t is hours worked.

The domain of this function is the number of hours you can work in a week—zero to 168. The range is the set of values p(t) can take on, which we have said is p(0) to p(168). This problem, however, is asking for the range for a typical 40-hour week. That will be p(0) to p(40):
the interval [0, 280].
