Once your friend has thought of a number, do the following:
1. Ask him or her to multiply the chosen number by 2.
2.Choose an even number to use yourself. Ask your friend to add this number to the one in his head.
3.Tell him/her to divide the new number by 2.
4.Tell your friend to subtract his original number from the equation.
5."Guess" the number.

There is not an answer to an expression.
-3+p is an expression, unless there was an equal sign and a sum at the end, that is when we can solve for the variable x.
-3+p simply equals -3+p
Using the classification for even and odd functions, it is found that the function is even, because f(-x) = f(x).
<h3>How we verify if the function is even, odd, or neither?</h3>
- If for all values of x, f(x) = f(-x), the function is even.
- If for all values of x, f(-x) = -f(x), the function is odd.
- If neither of these statements are true, the function is neither even nor odd.
Graphing the function 
, for every value of x, f(x) = -f(x), that is, the function is symmetric over the y-axis, hence it is even.

Hey there! :)
Answer:
A. x = 5.
Step-by-step explanation:
Starting with:
4x + 1 = 21
Subtract 1 from both sides:
4x + 1 - 1 = 21 - 1
4x = 20
Divide both sides by 4:
4x/4 = 20/4
x = 5.
The first roller coaster is 35 for 5 which means $7 for 1 ride
the second roller coaster is 59 for 11 which means 59 divided by 11 get 5.36
5.36 times 11 = 58.96 probrably a combo so it is estimated upward
