A reciprocal is the inverse of a number.\nSo -20/1 reciprocal is 1/-20.

Mathematics   The even or odd quality of an integer. If two integers are both odd or both even, they are said to have the same parity; if one is odd and one even, they have different parity.\n\nthat's the definition of parity but i can't remember using the term parity when i did polynomials a few years ago.\n\nall i remember is if the first term was negative, the first movement would be down in the graph. if it was x^2 there was one minimum/maximum, x^3 one minimum and maximum, x^4 three minimums/maximum etc\n\nthe other thing i remember is that you never need this information again unless you do further education that involves this.\n\ngood luck.

First, change any mixed number into improper fraction.\n\nThen, I will show you how to divide fractions.\nThink of a, c as the numerators and b and d as denominators. Then you want to divide a/b by c/d. It will be written like this:\n(a/b)/(c/d)\n\nGet the reciprocal of(invert) the divisor, and multiply it to the dividend\n\nthe reciprocal of c/d is d/c, so\n(a/b)/(c/d) = a/b x d/c\n\nmultiply them now\n(a x d)/(b x c)\n\n^_^

Please explain what is ~f.  I have curiosity, because neither inverse multiplicative, complex conjugate or inverse function could do that result...\n\nIt should be interesting!! Please post what is ~f !

C opposites\n\nNote: I have never seen analogies use the same word\nin both the question and the answer. So that eliminates\nB and D. Since unfavorable is the opposite of favorable,\nwhat is the opposite of forthright?

reciprocal means 1/(5x-10) \nwhen is 5x-10=0?\nwhen x=2, 1/0 is undefined, therefore the vertical asymtotes is x=2\n\n1/(x^2-x-20)\nwhen is x^2-x-20=0?\nby factorising (x-5)(x+4)=0\nwhen x=5 or x=-4,\ntherefore the vertical asymptotes are x=5 and x=-4\n\nboth of the graph horizontal asymptotes is the x-axis because it does not cut x-axis

I assume you are asking for the inverse of f(x)\n\nThen f-1(x) = (x+1/3)/2

the name i learned for this is fraction splitting\n\nyou can split into A/x + (Bx+c)/(x^2 + 1) \n\n( because x^2+1 is irreducible\nfor x = 1 and -1 the fractions should be zero that speeds up the calculation od A,B C, \nfinally write out and eqalt the corresponding fractions

Anything raised to the 0th power = 1.  Anything raise to the -1 power is its reciprocal.\n\ntherefore the first question is multiplying by 1.  Taking that, the solution becomes:\n\n(2x^-1)^3 * 1 = 1/(8x^3)\n\nThe second one is the reciprocal squared, so it's...\n\n(4/3)^2 = 16/9\n\nThe third one is as follows:\n\ny + 2 = 3/8(x-16)\ny + 2 = (3/8)x - 6\ny = (3/8)x - 8\n\n(hence m = 3/8 and b = -8)

It's the RECIPROCAL of the half life. The half life is the time it takes for the radioactivity intensity to decrease to one half of the intensity that was present at an arbitrarily selected starting time (t = 0), or the time it takes for one half of the radioactive atoms to convert (decay) to their new state (and possibly become new elements).

Multiplying by the reciprocal works as follows. \nSuppose you have 3 divided by 1/2, than that's equal to 3 time 2/1, according to the rule of multiplying by the reciprocal.\n3 /   (1/2 ) = 3 * (2/1) = 6\n\nNow let's start easy, 3 divided by 1, you know that's\n\n3 / 1 = 3\n\nBut now your dividing by something that's two times smaller, your dividing 3 by 1/2. You know if you have ever divided cake, if you divide a cake into half the number pieces you get twice as much! \nSo your answer is \n3 /1 * 2\n\nNow I rearrange this into \n3/1*2 = 3 * 2/1 so indeed 3/ (1/2) = 3* (2/1). This works for all numbers [ Try that yourself!].

when you say "negative" what that means is the opposite sign of the number. For example, the negative of -6 = 6 and the negative of 4.5= -4.5\n\nwhen you say Inverse correlation, you're talking about a relationship where you simply flip the fraction. for example... 3/4 becomes 4/3, and 5 becomes 1/5.

Answer: 1\n\nThis is a trick question to check people's power of observation\n\nHere it is given 1 = 5. Therefore 5 = 1

It looks like you are trying to solve a literal equation, which is an equation with more than one variable, and you have to solve for a specified variable.  You can use the SAME rules to solve this kind of equation as you do with regular equations (those with numbers).  For example, if you had 8=2(b)(9), you would divide by 2 and then again by 9 (which is like dividing by 18).  \n\nIf your problem is a=(1/2)bc^2, then you would divide by 1/2 and then again by c^2.  Remember that to divide by a fraction, you multiply by the reciprocal.
