If x > 0 then |x|/x = 1 !!!
If x<0 then |x|/x = -1
*below is an explanation! :)
_______________________________________
- I found the answer to this by choosing a any number that satisfies the requirement of x > 0 and plugging it into |x|/x
-----
Watch this!
Let's take 10 for example. 10 is greater than 0 like x>0 requires!
Let's plug it into |x|/x
|10| ÷ 10 = 1
*Remember that | | this means "absolute value" or whatever is in between the two bars will always be positive (+)
-------
Now let's take a random number that satisfies 0> x and do the same as we did above!
Let's take -3 and plut it into |x|/x
|-3| ÷ -3 = -1
Answer:
4x^2-7x+3
Step-by-step explanation:
(4x-3)(x-1)
4x^2-4x-3x+3
4x^2-7x+3
The areas will be in the ratio 1 : 1.5^2 = 1 .2.25
The area will be larger by a factor 2.25.
Answer:
the third one is the not the same with the first one
Step-by-step explanation:
Micheal has 40ft of fencing for the rectangular dog run. So the perimeter of the dog run is 40ft.
Perimeter=40ft
The perimeter of a rectangle is:
P=2l+2w
Since we know the length is 5 and the perimeter is 40, we can solve for the width.
P=2l+2w
40=2*(5)+2w
40=10+2w
subtract 10 from both sides
30=2w
divide both sides by 2
15=w
The width of the fence is 15feet.
