Oxana [17]

The linear function for the number of trimmers assembled is:

y = 7 + 4x.

--------------------------------

A linear function has the following format:

y = ax + b

In which:

  • a is the rate of change.
  • b is the fixed amount.

--------------------------------

  • In an earlier shift, 7 trimmers had already been produced, thus 7 is the fixed amount, that is, b = 7.
  • Diane assembles 4 trimmers per hour, thus the rate of change is 4, that is, a = 4
  • The <u>amount of trimmers y produced after x hours</u> is given by:

y(x) = 4x + 7

Amy,Ruben,and Sam have a total of $71 in their wallet. Sam has 3 times what Reuben has. Reuben has $9 more than Amy. How much do
iogann1982 [59]
Total = amount Amy has(A) + amount Ruben has(R) + amount Sam has(S)
S = 3 * R
R = A + 9

S = 3 * (A+9)
S = 3A + 27

71 = A + (A + 9) + (3A + 27)
71 = 5A + 36
5A = 35
A = $7

R = A + 9
R = 7 + 9
R = $16

S = 3 * R
S = 3 * 16
S = $48
