Question

1. which graph represents the solutions of the inequality z < 7? copyright © savvas learning company llc all rights reserved.

Explanation:

Step1: Analyze inequality $z<7$

The inequality means all values of $z$ are less than 7. On a number line, this uses an open circle at 7 (since 7 is not included) and an arrow pointing left (towards smaller numbers).

Step2: Match to the correct graph

Compare to the options:

• First graph: Closed circle at 8, arrow right (represents $z\geq8$)
• Second graph: Open circle at 7, arrow right (represents $z>7$)
• Third graph: Open circle at 6, arrow down (represents $z<6$)
• Fourth graph: Open circle at 7, arrow left (represents $z<7$)

Answer:

The fourth graph (open circle at 7, arrow pointing left towards smaller numbers)
