Presentation Transcript

Slide 1: 

Solving Inequalities Using Addition, Subtraction, Multiplication and Division

Slide 2: 

Addition Property of an Inequality….. …..Allows you to add the same value to each side of an inequality. If a > b, then a + c > b + c If a < b, then a + c < b + c

Slide 3: 

Solve using + n – 10 > 14 n – 10 + 10 > 14 + 10 n > 24 Add 10 to each side Simplify

Slide 4: 

Subtraction Property of an Inequality….. …..Allows you to subtract the same value to each side of an inequality. If a > b, then a - c > b - c If a < b, then a - c < b - c

Slide 5: 

Solve using - y + 7 > 12 y + 7 - 7 > 12 - 7 y > 5 Subtract 7 from each side Simplify

Slide 6: 

Division Property of an Inequality If you divide each side of an inequality by the same positive number, the direction of the inequality symbol remains the same. If a > b and c is positive, then a c > c b If a < b and c is positive, then a b c c <

Slide 7: 

Division Property of an Inequality If you divide each side of an inequality by the same negative number, the direction of the inequality symbol is reversed. If a > b and c is negative, then a c < c b If a < b and c is negative, then a b c c >

Slide 8: 

Solve using -3y < -27 -3y > -27 y > 9 Divide each side by -3 Reverse the symbol - 3 - 3 Simplify

Slide 9: 

Multiplication Property of an Inequality If you multiply each side of an inequality by the same positive number, the direction of the inequality symbol remains the same. If a > b and c is positive, then a . b > b . c If a < b and c is positive, then a . b < b . c

Slide 10: 

Multiplication Property of an Inequality If you multiply each side of an inequality by the same negative number, the direction of the inequality symbol is reversed. If a > b and c is negative, then a . c < b . c If a < b and c is negative, then a . c > b . c

Slide 11: 

Solve using y < -16 Multiply each side by -8 Reverse the symbol Simplify -8 y > 2 y -8 < 2 -8 -8
