Hey what do you think we do first?

amenah8 · Answer

First, like any equation, we would subtract 9 from both sides, right?

jagr2713 · Answer

Coreect so what do we get?

kash_thesmartguy · Answer

We take the constant off. So subtract 9 from both sides. There is your answer

jagr2713 · Answer

No @Kash_TheSmartGuy

amenah8 · Answer

-2 (greater than/equal to sign) -p would be the answer?

kash_thesmartguy · Answer

No, - and - equals positive. your answer will be in positive

jagr2713 · Answer

so we subtract and get -2 so now we have''

−2≥−p

now Multiply both sides by −1

what do we get?

kash_thesmartguy · Answer

2 is greater than or equal to p

amenah8 · Answer

I agree,the answer is 2 is greater than or equal to p, but IXL says that p is greater than or equal to 2. WHy are they doing this? IXL is adding p to both sides.

kash_thesmartguy · Answer

IXL is wrong!

jagr2713 · Answer

Yes i agree to its 2 :D

Its just that she said subtract 9 and thats your answer but you forgot to multiply by -1

amenah8 · Answer

Yeah, it's wrong on MANY occasions. Thanks, everyone!

kash_thesmartguy · Answer

anonymous · Answer

$$-2 \ge-p$$
multiply by -1
$$2\le p$$
or $$p \ge 2$$
