OpenStudy (xapproachesinfinity):

what do you think

OpenStudy (yanasidlinskiy):

The multiplicative Inverse of ANY number except zero, is 1 over the number.

OpenStudy (xapproachesinfinity):

remember multi inverse needs to give you 1

OpenStudy (xapproachesinfinity):

what you need to know is that ax(1/a)=1 we say 1/a is the multiplicative inverse of a

OpenStudy (xapproachesinfinity):

so which of those if we multiply it by -3 gives 1

OpenStudy (anonymous):

3?

OpenStudy (xapproachesinfinity):

no -3x3=-9 not 1

OpenStudy (xapproachesinfinity):

-3x what=1

OpenStudy (anonymous):

OpenStudy (xapproachesinfinity):

OpenStudy (anonymous):
