Your quiz is tomorrow! Remember that you are allowed to bring 1/2 sheet of notebook paper with whatever notes you want for the quiz: front side only. The quiz has 14 questions and two bonus questions.
We reviewed today with the algebra top 10 list and a make-your-own-study-guide activity. Study your notes and your examples so that you don't get stuck. Practice makes perfect!
Review sheets were due today. Any review sheets that I don't yet have can be turned in tomorrow for half credit. I'm not taking review sheets that are more than two days late.

Domain, Range, and Graphing Functions Review
Today we looked at a few examples involving functions, equations of lines, and graphing on a coordinate plane. Remember that functions have input and output, so therefore, they must contain at LEAST two variables. Two variables mean that we can graph them on two axes (x axis and the y axis).
We can easily graph equations in slope-intercept form, which uses the equation y = mx + b. m is your slope, and b is your y-intercept. To graph, we start at the y-intercept and we go up/down and over depending on what our slope is. Recall that slope is "rise over run," so make sure to look at your y-value (in the numerator) first and your x-value (in the denominator) second.
Shout out to TJ Davis for getting really excited about graphing things on sticky graph paper, and shout out to everyone sitting near him for putting up with the excitement. Shout out to Kelsey Hodges for extreme focus and perseverance throughout today - nice work!

Absolute Value Equations
Absolute value equations have two answers: one on the positive side and one on the negative side. We need to get the absolute value by itself on one side of the equation. Then, we need to solve the equation twice: once regularly, and once by flipping the signs of everything on the opposite side of the equation. We will have two answers when we are finished. NOTE: just because you are making two equations, one with a positive side and one with a negative side, does not mean that you have to have both a positive and a negative answer. You can have two negative answers, two positive answers, or one of each.
Five extra bonus points if you solve and graph this equation correctly and bring it into me by Friday, August 31st: 4|2c + 2| > 4c + 10. Good luck!
Shout out to Zadie Williams for her incredibly neat work and perseverance in a room full of upperclassmen! Great job! Shout out to Destiney Barnes for being the smartest person at Marion High School last year!

Inequalities Review
Inequalities are statements using greater than or less than - they contain multiple solutions. We use an open circle on the number line to represent < or > and a closed circle to represent greater than or equal to, less than or equal to.
Don't forget to flip the sign of the inequality if you are multiplying or dividing by a negative number!
In compound inequalities, "and" is when the arrows come together on the number line, and "or" is when they go in the opposite direction.
In equations or inequalities that contain fractions, you can always multiply out the denominator rather than changing it into a decimal. Not necessary but it's a nice trick to use if you like working with whole numbers rather than decimals.

Factoring/Solving for a Variable
When factoring, find the common factor (can be a variable OR a number!) and take it out of ALL your terms. It MUST be in all terms in order for you to take it out. For example, we cannot take the x out of the expression 2x + 5y + 7x because the 5y does not have an x.
To solve for a variable, use PEMDAS backwards and take variables/numbers away from each side, step by step, until the variable you are solving for is by itself. You should have the SAME VARIABLES in your answer as when you began.
Shout out to Sandra Hatcher and LeDarius Henderson for getting the ultra-challenging candy question, and shout out to Shanice Prater, Candace Latham, Khadijah Hamilton, Kassie Tittle, Kyndra Hunter, Brittany Ivory, and Regina Jordan for staying after class to learn how to solve it!

Equations Review
We reviewed some tougher equations today and may/may not have became frustrated by solving equations with fractions (Hint: It might be helpful to turn them into decimals first). We then looked at a really tricky problem involving a sidewalk, a pool, and perimeter.
In problems where our answer is a number = the same number, like 2 = 2, remember that the equation has infinite solutions! Any number that we plug in will work for the answer!
Shout Out to Shannon Reynolds for completing her ENTIRE review sheet already - wow, absolutely blown away by your hard work and dedication! You're awesome!

Pre-Test Day
We took the pre-test today - GREAT EFFORT on everyone's part to remember concepts and skills from Algebra 1! Seriously impressed here. If you didn't take the pre-test then you have until next Tuesday, August 27th, to make it up, otherwise it's a zero. A great time to do that would be during my service period (3rd), during my lunch (3rd lunch) or after school.
The first review sheet was given out today. You have until Thursday, August 29th to get it done. If you give it to me a day early, I will give you 5 bonus points.
Shout out to Michael Clayton for giving certain people in 7th period a pep talk about keeping their heads off the desk during class! Shout out to Regina Jordan for moving seats without complaining - thanks! I appreciate it :)

Welcome to Algebra 2! I'm so excited to be teaching this class this year, and I know that there will be tons of learning going on. My goal is for everyone to master enough Algebra 2 to achieve a 25 or higher on the math section of their ACT college entrance exam. To do this, you'll need to put in a lot of hard work, but I promise it will be worth it in the end.
We went over the syllabus in class today and filled out a student survey. I explained my expectations for the class as well as what it takes to be successful in room 215. If you missed class, please grab a syllabus tomorrow.
Homework: Bring back signed syllabus to class. +5 bonus points if I get it Tues. Aug. 20th. Regular credit if I get it Wed. Aug 21st. No credit if it's late.
