Question

-4z<-32 choose the correct graph for the inequality?

Answer 1

Answer: Choice C

The solution is $z \ge 8$

The graph has an closed filled in circle at 8 on the number line, with shading to the right of that closed circle.

=======================================================

Explanation:

$-4z \le -32$

$\frac{-4z}{-4} \ge \frac{-32}{-4}$ see note below

$z \ge 8$

note: I divided both sides by -4 to undo the multiplication done to z; the inequality sign flips because we divided both sides by a negative number

So the solution set is the set of z values such that z is 8 or larger. We are including the endpoint 8 so we use a filled in closed circle (not an open circle or hole). We include the endpoint because of the "or equal to" as part of ht inequality sign.
