Answer: f(0) = 5.5 f(2) = 3.7
<u>Step-by-step explanation:</u>

When x = 0, f(x) = 5.5 <em>In other words, f(0) = 5.5</em>
When x = 2, f(x) = 3.7 <em>In other words, f(2) = 3.7</em>
Answer:
(0,0) is among the solutions
Step-by-step explanation:
The given inequality is 
A solution to this inequality is any ordered pair that satisfies the inequality.
Let us check for x=0 and y=0
We substitute to get:

....This is true.
Therefore (0,0) is a solution to the given inequality.
There are infinitely many solutions.
Answer:
1. 1050
2. 200 x 5.25= C
3. 155 students
Step-by-step explanation:
1. 5.25 x 200= 1,050
2. you multiply 200 x 5.25 the c is the unknown cost
3. To find how many tickets were purchased you need to divide 813.75 by 5.25
