My best interpretation of the math here is that you're talking about the line integral,
I won't bother trying to decipher what look like multiple choice solutions.
By Green's theorem, the line integral above is equivalent to
where D is the set
Compute the double integral:
Answer: It’s y= 1/3x + 4
Step-by-step explanation: Because if you try to graph it then you get the points right. 4 will be on the y-axis of the chart.
The easiest way, I think, is to convert the mixed number into an improper fraction, then multiply by 3.
3 1/2 = 7/2
7/2 · 3 = 21/2
now just change the improper fraction back to a mixed number by dividing and putting the remainder into fraction form
21/2 = 10 1/2
You could also multiply the whole number by 3 and the fraction by 3, ending up with 9 3/2, but then have to convert the improper fraction into a mixed number
3/2 = 1 1/2
then add the numbers together
9 + 1 1/2 = 10 1/2
either way works, whatever is easiest for you.
