@iGreen

Answer 4

It's true.

x - 5 < 2

Add 5 to both sides:

x < 7

Answer 5

Inequalities are solved exactly the same way you solve equations.











True










False

Answer 6

Not \(exactly\), per say.

Answer 7

hmm.. idk

Answer 8

I don't know..I'd probably go with false..since you do isolate \(x\) by doing the opposite to both sides..however the signs are different and there are different rules(ex: When dividing by both sides of the equation by a negative number, you switch the sign)

Answer 9

k, thxs

Answer 10

Answer 14

Answer 15

Less than or equal to :)

Answer 16

\(\leq\)

Answer 17

The answer to that is false..

Answer 18

At most means it will include that number..but that's GREATER THAN.. For example, x > 2, that means x is more than 2, and it can't be 2.
