Answer:
y=|x|
domain= (-∞,+∞) range= [0,+∞)
y=-|x|
domain= (-∞,+∞) range= [0,-∞)
y=|x|-6
domain=(-∞,+∞) range= [-6,+∞)
y=4-|x|
domain= [-∞,+∞) range= [4,-∞)

Median is the number present in the middle when the numbers in a set of data are arranged in ascending or descending order.
Y = -4/5x + 8/5 (slope intercept form is y = mx + b)
Answer:
3
Step-by-step explanation:
To turn the word problem into an equation, when we read:
"I am thinking of a number" we write "x"
"when I double my number" we write "2x"
"and then subtract the result from 5" we write "5 - 2x"
"I get negative one" we write "-1 = 5 - 2x"
Now we solve for the number, which is x.
<em>Equation: </em>-1 = 5 - 2x
-1 = 5 - 2x
subtract 5 from both sides
-6 = -2x
divide both sides by -2
3 = x

There we go! The number is </h3><h2>
