*By*:-david

The perpendicular line through the origin is

.. y = (-1/5)x

The point where these lines intersect is

.. (-1/5)x = 5x +4

.. x = -4/(26/5) = -10/13

.. y - what's up? math?

pls use Gauss Elimination method to calc:

3x-y-2z=2

-2y-z=-1

3x-5y =3

Ans: no solution

Can you give me the reason/steps to show it has no solution - If x^2-y^2=10 and x-y=2 then x+y= a) 3b) 4c) 5d) 7e) 8?
*By*:-Michelle

x^2 - y^2 = 10

(x + y)(x - y) = 10

(x + y)(2) = 10

x + y = 5

[ x - y ] [ x + y ] = 10

2 [ x + y ] = 10

*By*:-Como

( 1 x i ) / ( i x i ) = ( 1 x i ) / ( - 1 ) = - i

1/i

= i/i^2

= i/-1

= -i

1/i × i/i = i/i² = i/(-1) = -i

What is the absolute value of the number:

-1+3i - In the equations x=7, what are the domain and the range?
*By*:-Ahmed

Domain is {7}, as x = 7 is a vertical line and it restricts x to this value. But there's no restrictions on y, so the range is all real y, or (-oo, oo).

*By*:-Noureen

g(x) = x^4, h(x) = (x/2),

gh(x) = g[x/2) = (x/2)^4 = x^4/16

g(h(5/2)) = (5/2)^4/16

= (625/16)/16

= 625/256

x/x = x^(1 - 1) = x^0 = 1. So 1 / x^0 = 1/1 = 1. x must be nonzero, though
