Question

Given: -1/2x > 6.

Choose the solution set.
a){x | x R, x > -12}
b_{x | x R, x < -12}
c){x | x R, x > -3}
d){x | x R, x < -3}

Answer 1

Divide both sides by -1/2. The trick here to remember that when you multiply both sides of an inequality by a negative number, the sign changes.
So you end up with x<-12
