Answer:
The inverse for log₂(x) + 2 is - log₂x + 2.
Step-by-step explanation:
Given that
f(x) = log₂(x) + 2
Now to find the inverse of any function we put we replace x by 1/x.
f(x) = log₂(x) + 2
f(1/x) =g(x)= log₂(1/x) + 2
As we know that
log₂(a/b) = log₂a - log₂b
g(x) = log₂1 - log₂x + 2
We know that log₂1 = 0
g(x) = 0 - log₂x + 2
g(x) = - log₂x + 2
So the inverse for log₂(x) + 2 is - log₂x + 2.
The Solution:
The correct answer is [option B]
Given:
Required:
To determine the inequality represented by the given number line.
Answer:
<h2><u><em>
False</em></u></h2>
Step-by-step explanation:
Is this true or false:
w(5)=w(-5)
we give the value 1 to w to keep it simple
1 ( 5 ) = 1 (-5 )
5 = -5
<em>It's false</em>
Answer:

Step-by-step explanation:
Two triangles are congruent by AAS postulate if two adjacent corresponding angles are congruent and the next adjacent sides to any of the angles is are also congruent. The adjacent sides should not be in between the two congruent angles.
From the triangles RQS and UTV

The adjacent side to
is RQ and for
is UT.
Similarly, the adjacent side to
is QS and for
is TV.
So, the possible sides that could be congruent by AAS postulate are:
or 
So, the correct option is 

From any proportion, we get another proportion by inverting the extremes (or the means):

= k
so we have:
2x=3k
2x+y=2k therefore:
3k+y=2k
y= - k
x=


= -

The corect answer is A. -3/2
or:

From any proportion, we get another proportion by inverting the extremes and the means:

We use a property of proportions:

where a, d are extremes and b,c are means and the product of the extremes equals the product of the means (a*d=b*c),
so we have

or

(you can check this also by "the product of the extremes equals the product of the means")



3y = - 2x
