Question

2p - 4p < _ -2
that is less than or equal to because I don't know how to make the symbol on my computer
Then I get -2p < _ -2
Divide both sides by -2 to get p > _ 1
Is that correct, that when you divide by a negative number the sign changes direction??

Because the answer book says p < _ 1

Answer 1

I agree with you ... p ≥ 1
... the direction changes if you multiply or divide by a negative quantity

alt-242 and alt-243 are ≥ and ≤

Answer 2

or on a Mac, the ≥ is obtained by pressing "option" >

btw, I agree with R_scott, the correct answer is p ≥ 1
