Solve |x| > 5

{-5, 5}
{x|-5 < x < 5}
{x|x < -5 or x > 5}

Last option.

Step-by-step explanation:

Given the inequality you need to set up two posibilities. These posibilities are the following:

- FIRST POSIBILITY :

- SECOND POSIBILTY:

Then you get that:

Therefore, through this procedure, you get that the solution set of the inequality    is this:

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
