Help with this anyone? (:

OpenStudy (anonymous):

go to mathway.com type in each of the equations until you get the write answer

OpenStudy (lifeisadangerousgame):

But I won't learn how to do it?

ganeshie8 (ganeshie8):

simplify each option and see if its true for every value of x

ganeshie8 (ganeshie8):

il do a, u will be doing the rest ok

OpenStudy (lifeisadangerousgame):

Okay

ganeshie8 (ganeshie8):

a. \(x^3 \ge x^2\) divide x^2 both sides (retriceuing x ne 0) \(x \ge 1\) which is not true when x = 0 so FALSE.

ganeshie8 (ganeshie8):

try other options

ganeshie8 (ganeshie8):

i typed 'a.s.suming x ne 0' lol

OpenStudy (lifeisadangerousgame):

B is wrong, if you plug in 2 for x then its 12 >/= 16 which is false

ganeshie8 (ganeshie8):

brilliant, verify remaining two

OpenStudy (lifeisadangerousgame):

haha I was trying to figure out why it was retrice XD

ganeshie8 (ganeshie8):

lol ikr....

OpenStudy (lifeisadangerousgame):

I think the answer is C

ganeshie8 (ganeshie8):

lets see :- \(\large (2x)^2 \ge 3x^2\) \(\large 4x^2 \ge 3x^2\) \(\large 4\ge 3\) which is always TRUE no matter wat happens in the rest of the world. so yess, answer is C

OpenStudy (lifeisadangerousgame):

Thank you ganeshie (:
