The coordinates of the intersection are the solution. Graphing Method: Graph each equation on the same graph. Substitution Method: Solve one equation for one variable and substitute that variable into other equations. The equations may need to be multiplied by a common multiple first. Divide by the number in front of the variable.Īddition/Subtraction Method: Combine equations to eliminate one variable.Get the variable on one side of the equal sign and numbers on the other.Multiplicative axiom: If a = b and c = d, then ac = bd Solving Equations And our Android/iPhone Prep App allows you to access that content on the go.Transitive axiom: If a = b and b = c, then a = cĪdditive axiom: If a = b and c = d, then a + c = b + d You can also choose between a live cohorted class with an instructor (which includes all our lessons and practice questions) or access to the self-study option by itself. Magoosh GRE prep offers lesson videos and practice questions to help you learn to put these formulas to use. You’ll also need to practice so that you know when it’s appropriate to use each formula. Like we mentioned before, simply memorizing these GRE math formulas is not enough.
(-8, 1) Show answer and video explanationĬonclusion: Is This All You Need for GRE Math? Which of the following points cannot lie on line k? In the xy-coordinate system, line k has slope and passes through point (0, 5). If the area of the triangular region enclosed by line k and the two axes is 30, what is the slope of line k?Ĩ. In the xy-coordinate system, line k has y-intercept 12 and an x-intercept greater than zero. If Pat weighs 126 pounds, what is Kim’s weight?ħ. Tuk weighs 60 percent more than Kim, Lee weighs 50 percent less than Tuk, and Pat weighs 25 percent more than Lee. If the percent increase from 2004 to 2005 was the same as the percent increase from 2005 to 2006, how much did Cindy have in this account in 2006?Ħ. In 2005, the amount in the same account was $5000. In 2004, Cindy had $4000 in a mutual fund account. If the average (arithmetic mean) score is 62, what is the value of x?ĥ. Ten students wrote a test, and the distribution of scores is shown on the frequency table. If the largest integer is 90, what is the least possible value of the smallest integer?Ĥ. The average (arithmetic mean) of 4 different integers is 75. If the circle with center O has area 9π, what is the area of equilateral triangle ABC?ģ. Given two other points B (4a, b) and C (2a, 5b), what is the area of triangle ABC in terms of a and b?Ĭlick here to view the video explanation.Ģ. Point A in the xy-coordinate system is shown below. Here are the most important GRE math formulas to know and practice before exam day! Geometry And you won’t get partial credit for showing your work, so picking the correct answer choice is very important! So study up the GRE math formulas cheat sheet and then practice using the formulas so you will know when they pertain to a question. Figuring out what each question is asking you to accomplish can be really tricky, whereas the math involved in solving them tends to be fairly straightforward. The thing that takes these concepts to the GRE level is their complexity. They DO INCLUDE things you’ve probably long forgotten like properties of shapes, integer properties, exponent rules, and word problems. These concepts DO NOT INCLUDE higher level math like trigonometry, calculus, or geometry proofs. The GRE Quantitative Reasoning section tests concepts that you likely learned during sophomore and/or junior year of high school. Knowing which math formulas to use, then using them quickly and correctly, can really help you do well on GRE quant. Memorizing this GRE math formula cheat sheet is just the first step to mastering GRE math.
