Explore and solve compound inequalities, graphing temperature ranges and electric voltage limits. Understand non-liquid state of water and refrigerator voltage requirements.
E N D
AND- the region the two graphs have in common OR- all of the regions given by the two graphs
Solve and graph the inequality. -5 ≤2x + 3 < 7
Solve and graph 6x - 5 < 7 or 8x + 1 > 25
Solve and graph • -3 < -1 - 2x ≤ 5
Write an inequality that describes each condition and sketch its graph. 1) Water is a non-liquid when the temperature is 32 °F or below, or is at least 212° F. 2) A refrigerator is designed to work on an electric line carrying from 115 volts to 120 volts.
