Answer:
B,C,D, and E
Step-by-step explanation:
Inequality tells us about the relative size of two values.
Mathematics is not always about "equals", sometimes we only know that something is greater or less than.
Example: Alex and Billy have a race, and Billy wins!
What do we know?
We don't know how fast they ran, but we do know that Billy was faster than Alex:
Billy was faster than Alex
We can write that down like this:
b > a
(Where "b" means how fast Billy was, ">" means "greater than", and "a" means how fast Alex was)
Inequalities: Symbols and Vocabulary
Algebra rules / General Rules:
ο· Isolate a positive x on the left side using algebra
ο· Reverse the inequality sign when mult/divide by a negative
οΌ Less than: The symbol that: ο Looks like an L (οΌ) for οΌess than
< β ) ο Points to the Left
ο£
β ] ο Caps the arrow pointing towards smaller numbers
on the number line
ο Points towards the smaller of two numbers (4 < 7)
> Greater than: The symbol that:ο Looks like the top of an R ( >
)for GReater than
> β ( ο Points to the Right
ο³
β [ ο Caps the arrow pointing towards larger numbers on
the number line
ο Open end is by the larger number (7 > 4)
Compound inequalities: usually in the form -4 < x < 4
but can also be x > -4 and x < 4
