How do you find the inequality of things? For example The temperature today will be at most 50 "F. Whoever answers first will get brainiest and 53 points.

Add (or subtract) a number from both sides.

Multiply (or divide) both sides by a positive number.

Simplify a side.

Step-by-step explanation:

Hope this helps:)

the answer is "add 2y and y"

step-by-step explanation:

you need to collect the like terms first.

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
