Question

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

x < –3; {–5, –3.6, –3, –0.8, 1, 1.5}

a. {-5, -3.6}
b. {-5, -3.6, -3}
c. {-3, -0.8, 1, 1.15}
d. {-0.8, 1, 1,15}

Answer 1

Answer: choice A {-5, -3.6}

To get this answer, first draw a number line. Mark -3 on the number line and place an open circle there. The open circle tells us that -3 is not part of the solution set. Anything to the left of -3 is shaded in to be part of the solution set. That includes numbers like -3.6 and -5 or anything smaller than -3
