Can someone please help me solve the inequality 3n+1

Question

Can someone please help me solve the inequality 3n+1<10^-4

anonymous · Answer

move the 1 from the left to the right
divide by 3

you don't need to worry about changing the direction of the equality unless you divide or multiply by a negative number

anonymous · Answer

Sorry its actuall 1/3n+1 < 10 ^ -4

anonymous · Answer

So I got to 3n+1 > 10^4

anonymous · Answer

$$\frac {1}{3n+1}>10^4$$ multiply by 3n+1, then divide by 10^4

anonymous · Answer

I think I got it.....Im doing remainders of series and the concept is just starting to sink in

anonymous · Answer

only worries for inequalities are multiplication by negative numbers (changes the sign of the equality) and absolute values, which is a bit more tricky. otherwise it's just like regular algebra

sorry i missed the -4 exponent in my answer there, what you got was correct
