Answer:
A. f(0) = 4
B. f(6) = 8
Step-by-step explanation:
When evaluating a piecewise function, the fist step is to determine the applicable domain. Then the function defined for that domain is the one that is used for the evaluation.
<h3>A.</h3>
x = 0 is in the domain x < 5, so the applicable function is f(x) = x+4.
f(0) = 0 +4 = 4
__
<h3>B.</h3>
x = 6 is in the domain 5 ≤ x < 7, so the applicable function is f(x) = 8.
f(6) = 8
Answer:the number of adult tickets that were sold is 160
the number of students tickets that were sold is $125
Step-by-step explanation:
Let x represent the number of adult tickets that were sold.
Let y represent the number of students tickets that were sold.
A total of 285 tickets are sold. This means that
x + y = 285
Adult tickets are $4 and student tickets are $1. A total of 285 tickets are sold for $765. This mean that
4x + y = 765 - - - - - - - - - - 1
Substituting x = 285 - y into equation 1, it becomes
4(285 - y) + y = 765
1140 - 4y + y = 765
- 4y + y = 765 - 1140
- 3y = - 375
y = - 375/-3 = 125
Substituting y = 125 into x = 285 - y, it becomes
x =285 - 125 = 160 tickets
