The reciprocal of any number or expression is one divided by that number or expression. In this case, you can also write -x + 3 as 3 - x; the reciprocal would be 1 / (3 - x). The parentheses are necessary, to indicate that you want to divide 1 by the entire expression. But if you write it in fraction form, with "3 - x" on the bottom, no parentheses are required.

What is three multiplied by one third?
3 x 1/3 = 1 (1/3 is multiplicative inverse or reciprocal of 3)
Simplify this expression - -x plus 3?
- - x + 3 = x + 3
What is the slope of a line perpendicular to line -2x 9y-8?
Without an equality sign and not knowing the plus or minus value of 9y it can't be considered to be a straight line equation. But in general the perpendicular slope is the reciprocal of the slope of the equation. As for example if the slope was 3 then its reciprocal is -1/3. And if its slope was -3 then its reciprocal would be +1/3
What is a reciprocal number?
The reciprocal of a fraction is obtained by interchanging the numerator and the denomator, i.e. by inverting the fraction. So, the number 3 (which is 3/1) would have a reciprocal of 1/3 And the reciprocal of 1/3 would be 3/1 ... or 3.
Multiply the following x plus 3 x plus 4 equals?
(x+3)(x+4) = x2+7x+12
What does reciprocal mean in mathmatical terms?
Reciprocal of 3 is 1/3 Reciprocal of 35 is 1/35. Reciprocal of x is 1/x. Reciprocal of 1/3 is 3. Reciprocal of 1/x is x. It is the inverse of a number.
A number three times its reciprocal is two?
Let's call the number x, then the reciprocal is 1/x 3/x is three times the reciprocal and that equals two. So 3/x=2 or3=2x and means x=3/2 Check it x=3/2 reciprocal is 2/3 and 3x 2/3=2.
The reciprocal of a number plus the reciprocal of twice the number equals one half?
Let the number be x.Reciprocal of x = 1/xReciprocal of x + Reciprocal of 2x = 1/x + 1/(2x) = (3/2)x = 1.5xIf the value of x = 1/3 then answer is one half.If the value of x = 2 then answer is 3.So, the statement is true only for x = 1/3.___________1/x + 1/2x = 1/2Multiplying both sides of the equation by 2x gives:2x/x + 2x/2x = 2x/2This simplifies to:2 + 1 = xx = 3 (i.e. the reciprocal is 1/3)
What is the reciprocal of a number plus the reciprocal of twice the number equals three over ten?
Let the number be x: 1/x+1/2x = 3/10 Multiply all terms by x: 1+1/2 = 3x/10 Multiply all terms by 10: 10+5 = 3x 15 = 3x Divide both sides by 3 to find the value of x: x = 5
The reciprocal of an integer plus the reciprocal of two times the integer plus two equals 2 over 3 Find the integer?
It is 2.
ASK FOR the product of a fraction and reciprocal show working?
By the definition of "reciprocal", any fraction multiplied by its reciprocal is equal to 1. For example:2/3 x 3/2 = 6/6 = 1a/b x b/a = ab/ab = 1By the definition of "reciprocal", any fraction multiplied by its reciprocal is equal to 1. For example:2/3 x 3/2 = 6/6 = 1a/b x b/a = ab/ab = 1By the definition of "reciprocal", any fraction multiplied by its reciprocal is equal to 1. For example:2/3 x 3/2 = 6/6 = 1a/b x b/a = ab/ab = 1By the definition of "reciprocal", any fraction multiplied by its reciprocal is equal to 1. For example:2/3 x 3/2 = 6/6 = 1a/b x b/a = ab/ab = 1

What does reciprocal mean in math?
A reciprocal is 1 divided by a number. So, the reciprocal of x is 1/x. For example: The reciprocal of 2 is 1/2 is 0.5 The reciprocal of 9 is 1/9 is 0.111111111111 The reciprocal of 0.5 is 1/0.5 is 2. To divide one by a number is called 'taking the reciprocal.' If you have a fraction, taking the reciprocal is fairly easy: simply 'flip' it. I.e., put the numerator in the denominator, and the denominator in the numerator. For example: The reciprocal of 2/3 is 3/2 The reciprocal of 7/8 is 8/7 The reciprocal of 1/4 is 4 (/1). The technical mathematical definition of the reciprocal of x is: "The number which, when multiplied by x, gives one."
