Answer:
the pre-image and the image are congruent
Step-by-step explanation:
What you do is move the equation around so the 12 -4.5x would now turn into y=-4.5x+12
Value of the expression will be 7
<u><em>Explanation</em></u>
Given value of the variables are :
and 
Given expression: 
So, <u>plugging the values</u> of
and
into the above expression, we will get...

So, the value of the expression will be 7.
Step-by-step explanation:
-k + 4(k + 1) = 2k
-k + 4k + 4 = 2k
-k + 4k - 2k = -4
(-1 + 4 - 2)k = -4
k = -4
Is this for money? Do you want an equivalent fraction? Please be more specific, but I'll imply a couple of options.
FOR MONEY:
50,000 euros is 55142.50 dollars
50,000 dollars is 45337.08 euros
Is 50,000 US dollars a good salary? In my opinion, yes. If you are a single person, and you work an office job from 9 to 5, then yes, that is a good salary.
MATH/NUMBERS:
50,000 = 100,000 ÷ 2
50,000 = 200,000 ÷ 4
50,000 = 25,000 × 2
50,000 = 12,500 × 4
There are other examples that could be used for both money and math, but I would not be able/do not have the time to list them all.
