### Transcript of "Algebra 5 Point 4"

1. 1. 5.4 Combining Inequalities<br />Objective: <br /><ul><li>To graph the solution sets of conjunctions & disjunctions of inequalities</li></ul>Frameworks: 10.P.1, 10.P.7<br />
2. 2. How would you graph a disjunction?<br />x < 2 or x = 2<br />The graph should contain all the solutions of the two sentences<br />
3. 3. Graph 11 – 3x ≤ 26<br />
4. 4. Graph x ≤ -2 and x > 3<br />
5. 5. Graph x ≤ -2 or x > 3<br />
6. 6. Graph x > 1 or x < 4<br />
7. 7. Graph x > 1 and x < 4<br />
8. 8. Graph x -1 ≥ -3 and 4 < 2x - 2<br />
9. 9. Graph x -1 ≥ -3 or 4 < 2x - 2<br />
10. 10. x > -1 and x < 4<br />can also be written as:<br />-1 < x < 4<br />This can be read as:<br /> -1 is less than x and x is less than 4<br /> x is greater than -1 and x is less than 4<br /> x is between -1 and 4<br />
11. 11. Graph -3 < 2x + 5 ≤ 9<br />
12. 12. Example<br />This year, Jim’s weight fluctuated within a 7-lb. range. At times, he weighed as little as 125 lb. At other times, he weighed almost 132 lb. Write a conjunction that describes the range of values for Jim’s weight.<br />125 ≤ x and x < 132<br />125 ≤ x < 132 <br />
13. 13. Turn to page 182<br />Do 1-20, 35-37<br />
