Solve the inequality. 3m ≤ –9 A. m ≥ –3 B. m ≤ –3 C. m ≥ 6 D. m ≤ –6

ganeshie8 (ganeshie8):

to solve, u must isolate the variable

ganeshie8 (ganeshie8):

m is the variable here

ganeshie8 (ganeshie8):

3m ≤ –9

ganeshie8 (ganeshie8):

wat should be done to isolate m ?

OpenStudy (anonymous):

idk

ganeshie8 (ganeshie8):

its okay :) observe that 3 is sticking to m

OpenStudy (anonymous):

ok

ganeshie8 (ganeshie8):

3m ≤ –9

ganeshie8 (ganeshie8):

we must get rid of it,

ganeshie8 (ganeshie8):

lets divide 3 both sides and see

ganeshie8 (ganeshie8):

3m ≤ –9 /3 /3 m ≤ –3

ganeshie8 (ganeshie8):

its isolated ! we have m all by itself !! so thats the solution

ganeshie8 (ganeshie8):

see if that makes some sense

OpenStudy (anonymous):
