Solve the inequality -2y - 7 11

Question

Solve the inequality -2y - 7 > 11

jamierox4ev3r · Answer

just solve this like a regular equation

-2y-7>11
     +7  +7
--------
-2y>18
now when you divide by a negative, FLIP the inequality sign!
-2y>18
/-2  /-2
------
y< __  see if you can figure out what y is less than from here :)

@SwagJones ? O.o

what is 18 divided by -2?

anonymous · Answer

haha i couldnt think of anything else sorry man... its -9

jamierox4ev3r · Answer

lolz its okay, so your answer is y<-9 :) does that make sense? or do you want me to go over the process again @SwagJones ?

anonymous · Answer

made perfect sense, could you also Describe the graph of the solution i dont get that

jamierox4ev3r · Answer

right then. All you have to do is just graph it like a regular equation, but with the inequality, shade below or above the line according to whether the inequality is less than, or greater than. Also, if the inequality is > or <, then the line (slope) is dotted) if the inequality is $\ge$ or $\le$, then the line would be solid

so for this problem, the graph would look like this :)|dw:1378500338721:dw|
