Study Notes
Inequalities and Graphing
- The inequality x ≤ 24 indicates that x can take any value less than or equal to 24.
- An open circle is used when graphing b < 6, indicating that b cannot equal 6.
- The inequality 9 ≥ -2m + 2 - 3 can be simplified to m ≥ -5.
- For the inequality 3(x - 2) < 2(x + 9), it results in x < 250.
- The statement s ≤ 18 expresses that the number of students is at most 18.
Graphing with Open and Closed Circles
- When graphing m ≤ 5, a closed circle is used to represent that m can equal 5.
- Similarly, an open circle is used when graphing x > -14, indicating x cannot equal -14.
- The inequality z < 7 is represented by an open circle, meaning z cannot equal 7.
Solving Inequalities
- To solve the inequality 12 ≥ 15 - 6y, the solution is y ≥ ½.
- For financial constraints, the inequality to determine monthly payments after a $400 down payment is 12x + 400 < 1200.
- The inequality -p - 4p > -10 simplifies to p < 2.
- The inequality 6x + 10 > 5x - 12 can be solved to show x > -22.
- The inequality -3 − 6(4x + 6) > -111 results in x < 3.
Multi-step Inequalities
- Solving 4(2a + 3) < 3(a - 1) provides understanding of operations involving variables and constants.
