Part 1 out of 3 The school store is running a promotion on school supplies. Different supplies are placed on two shelves.
You can purchase 5 items from shelf A and 4 items from shelf B for $46. Or you can purchase 4 items from
shelf A and 5 items from shelf B for $44. Write a system of equations that can be used to find the individual
prices for the supplies on shelf A and on shelf B.

f(x)=4

step-by-step explanation:

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
