Answer:
a. f(12) = - 1
b. x = 27 when f(x) = 4
Step-by-step explanation:
We are given that and we want to find f(12) and f(x) = 4
To find f(12) we simply plug in 12 into x and evaluate it
plug in 12
multiply 12 and 1/3 to get 4
subtract 5 from 4 to get -1
Now we want to find the value of x when f(x) = 4
To do this we substitute 4 for f(x) and solve for x
substitute 4 for f(x) and solve for x
add 5 to both sides
multiply both sides by 3
27 = x
And we are done.
So f(12) = -1 and x = 27 when f(x) = 4

Answer: 10 nickels
Step-by-step explanation:
A pennie is a cent or $0.01. Serenity has 12 pennies so the amount she has from pennies is:
= 12 * 0.01
= $0.12
The amount she has in nickels at most is therefore:
= 0.66 - 0.12
= $0.54
A nickel is $0.05 so the number of nickels are:
= 0.54/0.05
= 10.8 nickels
= 10 nickels
If she has 10 nickels then the total she would have is:
= (12 * 0.01) + (10 * 0.05)
= $0.62
<em>This fits the parameters </em>
