Question

solve the inequality. graph the solution set and write it in interval notation.

-9 \[\le\] -2x + 5 < 1 Is it (7, infty) or the other way around.

Answer 1

\[-9\le-2x+5<1\]?

Answer 2

yes that is correct

Answer 3

i just started using this so Im still trying to fig out how to use some of the signs...

Answer 4

\[-9-5\le-2x<1-5\]\[-14\le-2x<-4\]\[\frac{-14}{-2}\le x<\frac{-4}{-2}\]\[14\ge x>2\]\[(2,\infty)\]?

Answer 5

the last one I was wrong

Answer 6

wouldnt you divide the 2 over the 14 to get 7 or am I way off...

Answer 7

I caculator wrong

Answer 8

\[7\ge x>2\]

Answer 9

you r rite... I was looking at the graph wrong

Answer 10

−9−5≤−2x+5-5<1−5
−14≤−2x<−4
−14/2 ≤ -x < −4/2
−7≤-x<−2
\[7 \ge x > 2\]
or
2<x≤7

\[ x \in ]2,7] \]

Answer 11

|x|x>2 , x<=2|

Answer 12

no infty

Answer 13

got it.... thank you both very much

Answer 14

ty
