not true:(
OpenStudy (anonymous):
\[\frac{3}{2}y - 2x>1\] with \(x=4,y=1\) gives
\[\frac{3}{2}\times 1-2\times 4>1\] or \(\frac{3}{2}-8>1\) which is wrong
OpenStudy (anonymous):
so it is b?
OpenStudy (anonymous):
no B is wrong
OpenStudy (anonymous):
lets try (1, 1/4)

OpenStudy (anonymous):
ok so which one should i go with?
OpenStudy (anonymous):
ok
OpenStudy (anonymous):
i have no idea
you can't know it without trying them
OpenStudy (anonymous):
\[\frac{3}{2}\times \frac{1}{4}-2\times 1>1\]
\[\frac{3}{8}-2>1\] no so it is not C
OpenStudy (anonymous):
ok so we have a. d. and e left

\((1,0)\) does not work because \(0-2>1\) is false
OpenStudy (anonymous):
ok so i think a is right
OpenStudy (anonymous):
(1/4, 3/4)\[\frac{3}{2}\times \frac{3}{4}-2\times \frac{1}{4}>1\]
\[\frac{9}{8}-\frac{1}{2}>1\] nope
OpenStudy (anonymous):
gosh so its e?
OpenStudy (anonymous):
no

OpenStudy (anonymous):
so its none of the above?
OpenStudy (anonymous):
maybe A
(1/4, 1)\[\frac{3}{2}\times 1-2\times \frac{1}{4}>1\]
\[\frac{3}{2}-\frac{1}{2}>1\]
\[1>1\] hmm
OpenStudy (anonymous):
i don't see any that are right
OpenStudy (anonymous):
really:(?
OpenStudy (anonymous):
