Welcome to Room K 101's Blog. Check out the Weekly Notes from your class. With Math . you can do anything. Friday, January 16, 2015. Algebra ( Period 5). Graphing Systems of Linear Equations 6-1. If 2 lines are graphed on the same coordinate plane, one of three things will happen. 1They will intersect exactly once—we say they are CONSISTENT and INDEPENDENT. 2They will NEVER intersect; they are parallel or have the same slope (m) but different y intercepts (b)—we say they are INCONSISTENT.

Welcome to Room K 101's Blog. Check out the Weekly Notes from your class. With Math . you can do anything. Wednesday, April 15, 2015. Solving Quadratic Equations By Using the Quadratic Formula 9-5. Let's all sing it to "Pop Goes the Weasel! X = -b plus or minus the square root of b squared minus 4ac all over 2a. Notice how the first part is the x value of the vertex -b/2a. The plus or minus square root of b squared minus 4ac represents. How far away the two x intercepts (or roots) are from the vertex!

Transformations change the position or size of any figure. In Math 8 we are doing this with geometric figures like triangles and parallelograms. In Algebra we will do this with parabolas. Has the vertex at the origin but if you add 4 to the it,. The vertex moves up 4 on the y axis. If you add -4 { y = x. This ...

Square rooting "undoes" squaring! It's the inverse operation! Just as subtraction undoes addition Just as division undoes multiplication. If you square a square root:. 243 (what you started with). If you square root something squared:√243. 243 (what you started with). 8730;243)(√243) = 243. Answer: Either posit...

SOLVING QUADRATICS USING SQUARE ROOTING. We’ve been solving all quadratics with GRAPHING or the ZERO PRODUCTS PROPERTY after we get our happy face on and factor. There are several other ways to solve 2nd degree equations:. Square rooting both sides – Chapter 8-9 Example 4 on p. 525 with Chapter 10-2. The Quadratic Formula – Chapter 9-5. 5x -36 = 0.

The life story about someone who was so negative- you wanted to take a little negativity away but since you can't do that you add a little positiveness- works in math as well! Instead of subtracting . "ADD THE OPPOSITE! In life- to take away a little negative- add some positive. To take away an integer. add its opposite. Rule from our textbook.

Using Addition With Multiplication to Solve a System 6-4. This is still second Algebraic method to solve a system but to get the additive inverses of one variable—you will need to multiply ONE or BOTH equations by a factor. Multiplying just ONE equation. 5x 6y = -8. 2x 3y = -5. Multiply the bottom by -2 to eliminate y. 5x 6y = -8. 4x -6y = 10. 4x 2y = 8.
