Step-by-step explanation:
7) Algebraic Inequality: x ≠ 3
--> -∞ < x < 3 and 3 < x < ∞
Graph: ←o→
3
Interval Notation: (-∞,3) ∪ (3, ∞)
8) This is a duplicate question of #7
9) Algebraic Inequality: x ≠ 2 and x ≠ 7
--> -∞ < x < 2 and 2 < x < 7 and 7 < x < ∞
Graph: ←oo→
2 7
Interval Notation: (-∞, 2) ∪ (2, 7) ∪ (7, ∞)
10) Algebraic Inequality: x ≠ -4 and x ≠ 0
--> -∞ < x < -4 and -4 < x < 0 and 0 < x < ∞
Graph: ←oo→
-4 0
Interval Notation: (-∞, -4) ∪ (-4, 0) ∪ (0, ∞)
