has a clockwise orientation, so in order to use Green's theorem (which is probably the "theorem" mentioned here), we have
where 
is the triangle region.
Answer:
(3,6)
Step-by-step explanation:
Collect like terms
y -5x = -9
y + 2x = 12
Using elimination method
Subtract equation 2 from equation 1
y - 5x = -9
y + 2x = 12
---------------
0. -7x = -21
Divide both sides by -7
-7x = -21
---- -----
-7 -7
x = 3
Substitute x=3 into equation 1
y = 5(3) - 9
y = 15 - 9
y = 6
Solution is (x,y) = (3,6)
12$ per 3×3 if its square yard
so 180 ÷ 9 = 20
20×12$=240$
Answer: $6, 720
Step-by-step explanation:
Formular for simple interest =P×R×T
where;
P= 6000
R= 3% = 0.03
T= 4 years
$6000 × 0.03 × 4
= $720
The total amount to be paid back at the end of time will be
$6,000 + $720
=$6, 720
I hope this helps
