Thank you. I will use this lesson at the beginning of Algebra 2 as an intro and for me to pre-assess my students.

Solution without using a calculator: If we factor out x on the left side: x( -3 + 21p ) = 84 To get x in terms of p, you have to divide both sides by ( -3 + 21p ), so ( -3 + 21p) ≠ 0 since you can't divide by 0. So if ( -3 + 21p ) = 0, there is no solution for x. Now you can add 3 to both sides: 21p = 3 and divide both sides by 21: p = 3/21 = 1/7 So p ≠ 1/7

I feel like teaching "just type the exact question into the computer" is an innefective method for learning.

@susancarriker2 ай бұрын

You are right. I am not teaching content in these videos, I am "hacking" this test. I totally agree with you. Maybe one day SAT will be a memory and "hacking" will no longer be a strategy

@carymallon11522 ай бұрын

But couldn’t the student as quickly typed in (25*36)^0.5. ?

Absolutely! The strategy given is really only needed when you don't already know a simpler or faster method.

This is the Desmos Calculator. These Quick Tips are just offering strategies you may not have seen before. If you know of more efficient ways to solve these problems, then of course, you should do that. I am not suggesting any of these are "better" than some other method.

....is this the new mathematics??? Same variable (being w) so it straight up combine like terms with PEMDAS/BODMAS (I think BODMAS what taught with the former) so literally 20 - (4+3) which is 20 - 7 so 13 and addd the variable back on it to be 13w

@susancarriker2 ай бұрын

Definitely, you can distribute and combine like terms to get this answer, but the purpose of my quick tips are to give alternative strategies if you are stuck or need another method. All Quick tips involve using the Desmos calculator.

Most people would not use this method for this item, but this can be quite useful on more challenging items (like higher order polynomials, logarithms, radicals, trig, etc ..)

@@susancarriker Yes ofc I'm a 9t grade student and my test is tomorrow and I have been struggling with the rate of change and geometry do you think you can make a video going over those topics ?

@susancarriker2 ай бұрын

If you mean finding rate of change (slope), you can practice with this free activity: www.geogebra.org/m/kc7nezdh If you mean average rate of change, I have other video series (like STAAR, LEAP, etc) with examples that include average rate of change problems (Similar, because you are still finding slope between two points, just like the activity). I am doing an ACT Quick Tip video today over slope and parallel lines (so check that one out later this morning!). I don't have any geometry test prep videos yet, and I'm sorry I can't put one together today. But, if you have done the whole GMAS series and are comfortable with your Desmos calculator, you WILL do great! Don't you worry!!

In mathematics, the Pythagorean theorem, also known as Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. The theorem can be written as an equation relating the lengths of the sides a, b and c, often called the "Pythagorean equation":[1] a 2 + b 2 = c 2 , {\displaystyle a^{2}+b^{2}=c^{2},} where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides. Although it is often argued that knowledge of the theorem predates him,[2] the theorem is named after the ancient Greek mathematician Pythagoras (c. 570 - c. 495 BC) as it is he who, by tradition, is credited with its first recorded proof.[3][4][5] There is some evidence that Babylonian mathematicians understood the formula, although little of it indicates an application within a mathematical framework.[6][7] Mesopotamian, Indian and Chinese mathematicians all discovered the theorem independently and, in some cases, provided proofs for special cases. The theorem has been given numerous proofs - possibly the most for any mathematical theorem. They are very diverse, including both geometric proofs and algebraic proofs, with some dating back thousands of years. The theorem can be generalized in various ways, including higher-dimensional spaces, to spaces that are not Euclidean, to objects that are not right triangles, and indeed, to objects that are not triangles at all, but n-dimensional solids. The Pythagorean theorem has attracted interest outside mathematics as a symbol of mathematical abstruseness, mystique, or intellectual power; popular references in literature, plays, musicals, songs, stamps and cartoons abound.
