I gave you a medal

Answer 11

@Awolflover1 sorry for my intervention but when you divide by a negativ number dont necessary changing the sign > inversed <
so than i remember it right ?

@TheSmartOne ? please

Answer 12

Yes, you have to change the sign when you divide/multiply an inequality by a negative number

Eg.

-4x > 4

Divide -4 on both sides and change sign
x < -1

Answer 13

so x < -6 is the right answer

Answer 14

so this mean that choice a. is the right answer and not b.

Answer 15

TSO am i right please ?

Answer 16

−2x − 4 > 8

not b. so choice a. is the right answer bc.

x<-6

so for example x = -7

-2(-7) -4 >8
14-4 > 8
10 >8

but for choice b. so x>-6 so for -5

-2*(-5) -4 > 8
10 -4 >8
6 not is greater than 8 - this is false
