|x + 2| < 4
As neither x or 2 are negative, the bars do not matter and can be eliminated.
x + 2 < 4
Minus 2 from both sides, and because you subtracted, make sure to turn the 'less than' sign into a 'greater than' sign.
x > 2 is your answer
Answer:
(1 -2y)(1 +2y)
Step-by-step explanation:
The difference of squares is factored as ...
... a² - b² = (a -b)(a +b) . . . . . . . . a form you should keep handy
Here, you have a=1, b=2y, so your factored form is ...
... 1 -4y² = (1 -2y)(1 +2y)
Answer:
67
Step-by-step explanation:
First multiply, then do addition and subtraction in order from left to right
Assuming that this is a linear relationship you must find the rate of change...$23.81-$20.70= $3.11. 3.11 is how much it changed that year. What that also gives you is how much you bought the post for at 0 years by subtracting $20.70 and the $3.11 = the price of the poster. This gives us the equation y=3.11(x)+17.59
Where Y is the value and X is the amount of years.
