Inequality Solution set
CONCEPTS
Tips
• Flip the inequality sign when each side is multiplied or divided by a negative number
• When there are 2 inequality signs in an expression (ex: 1 < x < 3), then it means AND. Create 2 equations and solve for the variable. (x > 1 AND x < 3)
PRACTICE PROBLEMS
Question 1 Simplify the expression: 5 < x + 3 < 8
-- Answer -- y ≤ -a / B x + a
m = (a - 0) / (b - 0) = -a/B
y ≤ -a / B x + a
