-4x < 28

OpenStudy (anonymous):

x > -7

OpenStudy (anonymous):

when you have a negative exponent and you move it to the other side you have to change the sign

OpenStudy (anonymous):

so opposite with this one ? 8x < -32

OpenStudy (anonymous):

no not like that if it is -5x > 25 you change it like this x < 5

OpenStudy (anonymous):

x < -5

OpenStudy (anonymous):

so 8x < -32 is x > -4

OpenStudy (anonymous):

no if the number before the x is negative it changes the sign like -x you have to change the sign

OpenStudy (anonymous):

ok its only when you divide or multiply with a negative you change the sign

OpenStudy (anonymous):

okae . so what is 8x < -32 ?

OpenStudy (anonymous):

x < -4

OpenStudy (anonymous):

if it was -8x<32 it would turn out to be x>-4
