Answers:The additive inverse of a number x is a value y such that x + y = 0 (0 is the additive identity) The multiplicative inverse of a number x is a value y such that xy = 1 (1 is the multiplicative identity) Example: 1) Find the additive and multiplicative inverse of 7. 7 + y = 0 y = -7 So the additive inverse of -7. 2) Find the multiplicative inverse of 7. 7y = 1 y = 1/7 So the multiplicative inverse of 7 is 1/7. What you will learn: To find the additive inverse of any number, just take its negative and make its opposite sign. The additive inverse of 3 is -3. The additive inverse of -8 is 8. To find the multiplicative inverse of a number, just treat it as a fraction and then take its reciprocal.

Question:How do you find the additive inverse of these numbers? 246 - 37/53 -50.2 Here are some example, please use these to explane this problame to me, Thank You!

Answers:the additive inverse of one number is a number that sum up to 0 when added with the original number. for example, additive inverse of F is -F 246 --> -246 - 37/53 --> 37/53 -50.2 --> 50.2

Question:The question says to "graph each absolute- value function. Then graph the inverse on the same coordinate plane." I know how to graph, but how do you get the inverse?

Answers:To get the inverse of a function, first substitute x for y and y for x. Then solve for y. Example. Original: y=2x+5 New: x=2y+5, 2y=x+5, y=(x+5)/2 Example. Original: y=x^3 New: x=y^3, y=cube root(x)

Question:Can you help me identfity the additive and muliplicative inverse for the following numbers? -10 -0.125 4/3 How do you find the answer?

Answers:Additive inverses for numbers are nothing other than change the sign (make a + into a -, or a - into a +), you could also multiply by -1 to achieve the same goal. So the additive inverses for each are +10 +0.125 -4/3 The multiplicative inverse is the reciprocal, which means exchange numerator and denominator of an integer fraction. If it is not written as a integer fraction do so, or divide it by 1. So first rewriting your list as integer fractions -10/1 -0.125 = -1/8 4/3 (didn't change it was already an integer fraction) the multiplicative inverses are -1/10 -8/1 = -8 3/4 Notice for the multiplicative inverse you DO NOT change the sign.

Finding Inverse Matrix :Demonstration on how to find the Inverse of a 2 x 2 matrix.

College Algebra: Finding the Inverse of a Function :www.mindbites.com This lesson will teach you how to find the inverse of a function [f-1(x)] when you are given the function [f(x)] as a formula algebraically. Some functions, however, have no mathematically defined inverse. Professor Burger will show you how to recognize when a provided function has no inverse. For example, a parabola function cannot be inverted. This lesson is perfect for review for a CLEP test, mid-term, final, summer school, or personal growth! Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive course, College Algebra. This course and others are available from Thinkwell, Inc. The full course can be found at www.thinkwell.com The full course covers equations and inequalities, relations and functions, polynomial and rational functions, exponential and logarithmic functions, systems of equations, conic sections and a variety of other AP algebra, advanced algebra and Algebra II topics. Edward Burger, Professor of Mathematics at Williams College, earned his Ph.D. at the University of Texas at Austin, having graduated summa cum laude with distinction in mathematics from Connecticut College. He has also taught at UT-Austin and the University of Colorado at Boulder, and he served as a fellow at the University of Waterloo in Canada and at Macquarie University in Australia. Prof. Burger has won many awards, including the 2001 Haimo Award for Distinguished Teaching of Mathematics, the 2004 Chauvenet Prize, and the 2006 ...
