Question

help please... brain fart

Answer 1

lol

Answer 2

\[(-5/4x+9)<0\]

Answer 3

\[-\frac54x + 9 < 0\]
\[-\frac54 < -9\]
\[-5x < -9 \times 4\]
\[-5x < -36\]
FLIP ACTION!
\[5x > 36\]
\[x > \frac{36}{5}\]

Answer 4

(whispers) the 9 is under the denominator with the 4x... that is what i am having trouble with

Answer 5

soo..
\[ \frac{5}{4x + 9} < 0 \]
?

Answer 6

with a negative

Answer 7

yes

Answer 8

i havent done any rational inequalities... ever... but I think we're looking at when the graph is still negative, that would be where our denominator is greater than 0

that would be when 4x + 9 > 0
4x + 9 > 0
4x > -9
x > -9/4 x > -2 1/4

it looks like the graph would support this as well. its juts that I havent done any actual problems like this before! :P
