Answer:
The first one is linear the rest isn't
Step-by-step explanation:
A linear function represent a straight line.
The first one shows that.
The second function look more like a tangent function which is a trig function so it isn't linear. The third one is a exponential function which is definitely not linear.

Answer:
171
Step-by-step explanation:
Step 1: Let "x" and "y" be the variables
Let x = the number of adult tickets sold
Let y = the number of child tickets sold
Step 2: Add the variables and subtract the "x" variable
x + y = 486 y = 486 - x
Step 3: Add the given amounts by the variables next to it to equal the total
5.50x + 4y = 2416.50
5.50x + 4(486 - x) = 2416.50
5.50x + 1944 - 4x = 2416.50
Step 4: Subtracting the result from the number of tickets the booth sold
1.5x = 472.5
x = 315
y = 486 - 315 = 171
Therefore, there are 171 tickets of each type sold.
Answer:
B I'm not 100 percent sure that it's right but I'm pretty sure.
c/2-3+6/d
substitute c=14 and d=13:
14/2-3+6/13
simplify:
7-3+6/13
4+6/13
multiply 4 by 13/13 to group like terms (for a fraction):
52/13+6/13
combine:
58/13
Therefore, the answer is 58/13 or around 4.462
