@KamiBug any way you can help?
OpenStudy (kamibug):
In which one of those equations can you plug in 12 for f(x) and 8 for x and the equation will be true?
OpenStudy (kamibug):
Said simply, what number times 8 is 12? :)
OpenStudy (anonymous):
@KamiBug Is the answer 3/2x?
OpenStudy (kamibug):
You've got it! ^_^
