Katya treated everyone in theater to a pizza party. She bought 12 pizzas and six 2-liters of soda. The bill was $137.64 (before tax). The night before, Katya had bought one pizza and one 2-liter of soda for her family, and the bill was $11.95 (before tax). How much was each pizza? How much was each 2-liter of soda? Let x = the cost of each pizza in dollars
Let y = the cost of each 2-liter of soda (in dollars)
Cost of pizza:
Cost of 2-liter:

I need help with this word problem ASAP. Show work if possible! :)

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

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
