Identify the solution set of the inequality using the given replacement set.

x < –7; {–10, –7.2, –7, –6.9, 6.5, 9}

A. {–10, –7.2}
B. {–7, –6.9, 6.5}
C. {–10, –7.2, –7}
D. {–6.9, 6.5}

Answer 1

so in short, what the question is asking you, is as follows,\[x<-7\]so what numbers from your set\[{-10,-7.2,-7,-6.9,6.5,9}\]make the statement true? Remember that your inequality is that x is less than -7, meaning x can't equal -7, it has to be less than it

Answer 2

@Embryo I was think A, but I'm not sure >.>

Answer 3

Correct :D
A is the correct answer because -10 and -7.2 are both less than -7, if you are ever in doubt when dealing with negative numbers, draw a number line and mark each of your options, and then see which ones fit what you are looking for.
