Answer:
-2<x<4
Step-by-step explanation:
For , note that either the numerator or denominator is positive and the other must be negative for this inequality to be satisfied.
This means x+2>0 and x-4<0 or x+2<0 and x-4>0.
Lets look at the first scenario (x+2>0 and x-4<0)
x+2>0 and x-4<0
x>-2 and x<4
This means that -2<x<4.
Let’s look at the other scenario (x+2<0 and x-4>0)
x+2<0 and x-4>0
x<-2 and x>4
This means that x must be <-2 and >4 simualtaneously, which is impossible.
Therefore, this only occurs when -2<x<4.
I hope this helps! :)
the expression 30 tens - 3 tens 3 tenths. A number proceeded by "tens" means that the number is multiplied by 10 while "tenths" means that the number is divided by 10. 30*10 - 3*10*3/10 equal to 300 - 9 or 291.
