A). |x| = |-x|
This is always true.
The definition of 'absolute' value is 'size of the number without its sign'.
That's what this expression says.
b). |x| = -|x|
This is never true, because an absolute value is never negative.
This one would true if x=0 . So maybe some people might say
it's sometimes true, but that doesn't feel right to me. I say never.
c). |-x| = -|x|
This looks to me like exactly the same situation as (b),
and I would say all the same things about it.
<em>Answer:</em>
<em>x = 21/4</em>
<em>x = 5 1/4</em>
<em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>- 3/4 = x - 6</em>
<em>- 3 = 4(x - 6)</em>
<em>- 3 = 4x - 24</em>
<em>4x = 24 - 3</em>
<em>4x = 21</em>
<em>x = 21/4</em>
<em>x = 5 1/4</em>
<em>Good luck !</em>
Answer:
The numbers associated with the triangle are 5.437 and 6.437 centimeters, respectively.
Step-by-step explanation:
Two numbers are consecutives, when their difference is equal to 1. The area of the triangle is determined by the following formula:
Where is the shortest length of the triangle, measured in centimeters.
And we get the following second-order polynomial:
(1)
If we know that , then the shortest length of the triangle is:
and
Since length is a positive variable, the only possible solution is:
Then, the numbers associated with the triangle are 5.437 and 6.437 centimeters, respectively.
