Answer:
Step-by-step explanation:
f(x) =2x - 7
f( - 3) = 2( - 3) - 7 = - 13
f(3) = 2(3) - 7 = - 1
f(a) = 2a - 7
- f(a) = - (2a - 7) = 7 - 2a
f(a + h) = 2(a + h) - 7 = 2a + 2h - 7
Items bought:
x packs of pencils
twice as many packs of erasers, number of packs of erasers = 2x
three times as many rolls of tape, number of rolls of tape = 3x
Now, we have two possible scenarios:
1- The three items cost the same:
cost of one pack of pencils = cost of one pack of erasers = cost of one roll of tape = m
total amount spent = xm + 2xm + 3xm = 6xm
2- The three items do not cost the same:
cost of one pack of pencils = m
cost of one pack of erasers = n
cost of one roll tape = p
total amount spent = xm + 2xn + 3xp = x(m + 2n + 3p)
