8! mrs. curtis wants to buy online tickets for a concert. two options are given here. option 1: $53 for each ticket plus a shipping fee of $10 option 2: $55 for each ticket and free shipping what is a system of equations to represent the costs of the tickets? express your equations in the form of y=mx+b where x is the number of tickets purchased and y is the total cost.

y > 1/3x

y < = -x + 4

hope this : )

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
