Answer:
f(2) = 13.6
Step-by-step explanation:
Using the recursive formula and f(1) = 4 , then
f(2) = 0.4 f(1) + 12 = (0.4) × 4) + 12 = 1.6 + 12 = 13.6
C negative 4 :) Hope that helps!!

Answer: </h3><h3>Fred has <u>20 students</u> and Lee has <u>22 students</u></h3>
=============================================================
Work Shown:
L = number of students in Lee's class
F = number of students in Fred's class
Lee has 1.1 times as many students compared to Fred
This means we have this equation
L = 1.1F
Whatever the value of F is, we multiply that by 1.1 to get the value of L
The two amounts L and F add to 42 total students
L+F = 42
1.1F + F = 42 .... replace L with 1.1F
2.1F = 42
F = 42/(2.1)
F = 20 .... Fred has 20 students
L = 1.1*F
L = 1.1*20
L = 22 .... Lee has 22 students
------------
Check:
L+F = 22+20 = 42
this confirms the answer
1. it describes what the cost would be for two medium lattes and one small latte all together.
2. it would be the first one which is 2x + y = 7.15
