Presentation Transcript

Slide2 l.jpg

Solving One-Step Inequalities

Objective: To solve one-step inequalities using properties for inequalities


Slide3 l.jpg

Solving One-Step Inequalities

What are the Properties for Inequalities?

Are they the same as for regular equations?


Slide4 l.jpg

Solving One-Step Inequalities

Addition Property for Inequalities

X-15<73

X-15+15<73+15

Add 15 to

both sides

X<88


Slide5 l.jpg

Solving One-Step Inequalities

Subtraction Property for Inequalities

y+15<25

Y+15-15<25-15

Subtract 15 from both sides

y<10


Slide6 l.jpg

Solving One-Step Inequalities

Multiplication Property for Inequalities

Multiply both sides by the reciprocal of the coefficient


Slide7 l.jpg

Solving One-Step Inequalities

Division Property for Inequalities

Divide both sides by the coefficient of x


Slide8 l.jpg

Notice: Sign CHANGED

Division Property for Inequalities

Caution! Dividing by a negative number

Same if multiplying?


Slide9 l.jpg

…the sign CHANGES

Multiplication Property for Inequalities

Caution! When you multiply by a negative number…

YES!

-x > 2

5

x < -10

(-5 )-x > 2(-5)

1 5
