Which graph represents the compound inequality $h ≥ -5$ and $h < 2$?

Compound Inequalities Overview

Compound inequalities consist of two separate inequalities that can be connected by "and" or "or," representing a range of solutions.
Graphs visually represent the solutions to compound inequalities, highlighting open and closed circles for inclusive or exclusive values.

Graph of Compound Inequality for n

For the inequality n < -2 or n ≥ 4, the correct graph features an open circle at -2 pointing left and a closed circle at 4 pointing right.

Earnings Inequality

Dexter's earnings must satisfy 50 ≤ e ≤ 100, indicating he earns between $50 and $100, inclusive.

Graph Representation for n

The inequality -3 < n < 1 is represented by a graph with open circles at -3 and 1, connected by a line, indicating all values between -3 and 1 are included.

Compound Inequalities from Graphs

The graph that corresponds to the compound inequality -3 ≤ x < 1 features a closed circle at -3 and an open circle at 1.
Another graph illustrates the inequality x < -2 or x ≥ 4, indicating values less than -2 or greater than or equal to 4.

Actor Height Qualification

To qualify for a play role, an actor must be taller than 64 inches but shorter than 68 inches, represented as 64 < x < 68. This can also be expressed as x > 64 and x < 68.

Solutions of Compound Inequalities

The solution set for a compound inequality includes specific values; for instance, {-7, 5, 18, 24, 32} could satisfy the terms of an inequality.

Bolt Diameter Measurement

The acceptable diameter for a bolt ranges from 0.2 cm less than 1.5 cm to 0.2 cm greater than 1.5 cm, depicted in a graph with closed circles at 1.3 cm and 1.7 cm.

Clay Usage for Vases

For clay usage, Elisa's small vase requires no more than 4.5 ounces and the large vase requires at least 12 ounces, represented by the compound inequality c ≤ 4.5 or c ≥ 12.

Compound Inequality Graph for h

The graph for the compound inequality h ≥ -5 and h < 2 includes a closed circle at -5 and an open circle at 2, indicating the boundary values.
