High-density lipoproteins move cholesterol to tissues including arteries. The greater the level in the blood, the greater the risk for heart disease.

A deficiency in vitamin K causes:

Antioxidants protect cells from free radicals and limit the damage free radicals can do to the cells.

What is true regarding lactose sensitivity?

Scratch Paper Policy If testing in the Proctoring Center I will leave my scratch paper at the desk. I will, at my earliest availability, open up the Scratch Paper Assignment and submit a text entry stating I tested in the Proctoring Center. This lets the instructor know where to grab your paper if needed. If testing with Honorlock I agree to scan an upload my scratch paper(s) as a pdf file within 10 minutes of submitting my test so Catie knows the work was my own and was not copied from feedback or online app instructions. I will then submit the work in the Scratch Paper Assignment then destroy the paper. I will not share the questions or answers with any other person. By typing your first name below, you state that you am in compliance with maintaining the secrecy of the test questions.

Combine like terms to write simplified expressions Use the distributive property/inverse AND combine like terms to write a simplified expression. Problem 1 12 + 7x – (2x + 18)  The simplified expression is [a] Problem 2 14 + 3x – 5(x – 4) The simplified expression is [b]

Factoring Review Factoring asks you to look at all the terms and divide out the largest common factor they all share. We don’t get rid of this factor, we place it in front of the parentheses. The amount left after that value has been divided out is what remains within. Example: 6p + 18q – 24, 6 is the largest factor that evenly divides out of all the terms. Divide 6 out and keep its partnering factors/variables behind. 6(p + 3q – 4). I know this is accurate because I can distribute the 6 back in and get 6p + 18q – 24 to check myself. If I wrote p + 3q – 4, I would not have an equivalent expression. This would be 6 times less than its original value. Also, we never have a coefficient of 1 on our variable.

Combining Like Terms Algebra likes simplicity. Why have thing that are alike it more than one place? Like terms mean values that have the exact same variable (x and -3x or -2b and 10b) or no variable (constants like 15 and -18). When combining like terms, remember that terms with different signs must be subtracted from one another then keep the larger sign for the answer. If the terms have the same sign, you must add them together and keep the sign. -12x + 8x = -4x -4y – 6y = -10y Inverse Whenever there is a negative sign in front of parentheses, this means the inverse or “opposite of” what’s inside. If there is a negative number in front of the parentheses, that negative is a part of the distributive process. -(-3x + 7) becomes 3x – 7 -4(m – 4n) becomes -4m + 16n

Write a phrase for the algebraic expression (turn the numbers and operations into words). Avoid using “more than” to say addition. 4(x + 5)

Order of Operations Apply the order of operations to simplify (solve) these expressions. Don’t forget your calculator to help you navigate the signs.  Problem 1
