9.8. Inequalities with Constants
Solving an inequality with a constant means finding values for x in terms of the constant that make the inequality true.
Type the inequality as given in the problem with one inequality per line.
Examples
Solve each inequality in terms of the constants: a, b and c.
Type the inequality as given in the problem with one inequality per line.
Examples
Solve each inequality in terms of the constants: a, b and c.
1) 2x + a > 5
2) 3y – 2b + c < 0
3) 2y ≥ 12 – c
4) 3x2 – 2x > 4a + 1
5) 2x – 3a ≤ 12
2) 3y – 2b + c < 0
3) 2y ≥ 12 – c
4) 3x2 – 2x > 4a + 1
5) 2x – 3a ≤ 12
Calculator solutions
Type the greater than sign ( > ) by tapping the closed parentheses " ) " three times.
Type the less than sign ( < ) by tapping the open parentheses " ( " three times.
To enter the constants a, b, and c, use the a-z keyboard. To enter y as a variable, tap the x variable key twice.
1) Enter the expression: 2x + a > 5.
2) Enter the expression: 3y - 2b + c < 0.
3) Enter the expression: 2y > 12 - c as "2y >= 12 - c."
4) Enter the expression: 3x^2 - 2x > 4a + 1.
5) Enter the expression: 2x - 3a < 12 as "2x - 3a <= 12."
