In the case above, Talib work is not correct as one need to first switch x and y before one can solve for y.
<h3>What is the variables about?</h3>
Note that:
y=-8x+4
y-4=-8x
(y-4)/-8=x
Since the independent variable x is known, one can switch the variable labels and thus it will be:
y=(x-4)/-8
f^-1(x)=(x-4)/-8
This can be written again as:
f^-1(x)=(4-x)/8 :P
Thus one can say No, as he forgot to switch the variable labels after solving for the independent variable.
In the case above, Talib work is not correct as one need to first switch x and y before one can solve for y.

Answer:
enrollment decreases by 14.34%.
Step-by-step explanation:
Given that number of students enrolled in 2000 = 823
Given that number of students enrolled in 2010 = 705
705 is less than 823 so that means number of students enrollment is decreasing.
Decrease = 823-705 = 118
Percent decrease is given by formula:
which is approx 14.34%.
Hence final answer is that enrollment decreases by 14.34%
<h3>Roman numerals</h3>
Numbers are written as combinations of letters.
<h3>Taking into account that:</h3>
- x = 10 ⇒ (It is repeated twice)
- v = 5
- lll = 3 (To form this number, the "I", it can form itself up to 3. From 4 it changes.)
We do a sum of roman numerals
X + X + V + III = XXVIII
10 + 10 + 5 + 3 = 28
The Roman numeral <u>XXVIII</u> corresponds to the number 28 (twenty-eight).
