What is the multiplicative inverse of 1/2 ? User: What is the multiplicative inverse of one and a half ? **Weegy:** In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x-1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a. [ For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4. The reciprocal function, the function f(x) that maps x to 1/x, is one of the simplest examples of a function which is self-inverse. ] **User:** Evaluate A2 for A = -3.

x2 - 10xy + 3y + y2 - 1 **Weegy:** There are 3 terms. x, y, and xy.anything else? **User:** Integers are _____ irrational numbers.
**Weegy:** An Irrational Number is a real number that cannot be written as a simple fraction. Example: (Pi) is a famous irrational number. Pi = 3.1415926535897932384626433832795 (and more...). You cannot write down a simple fraction that equals Pi. [ ] **User:** Which of the following shows the correct order of the numbers below?

= 21 - 6 * 2
= 21 - 12
= 9 **User:** Simplify 9 - {x - (7 + x)}. **Weegy:** (x - 5)(x + 2) x^2 -5x + 2x - 10 = x^2 - 3x - 10 **User:** Evaluate + , if x = 10, y = -5, and z = -2.
**User:** Evaluate 7 + (-3x2) for x = 0.
**Weegy:** Solution :
(4x^2 ? 2x + 3) ? ( -3x^2 + 2x ? 5)
4x^2 ? 2x + 3 + 3x^2 - 2x + 5 =
7x^2 - 4x + 8 (answer) (More)

The coefficient of (-x)(3y)(-2x) is 6.

(-x)(3y)(-2x) = 6x^2y

(-x)(3y)(-2x) = 6x^2y
