Check this f(x) = 2.5x – 10.5 (x=12) 2.5*12= 30 30-10.5= 19.5 f(x)= 19.5

OpenStudy (anonymous):

so then 12=2.5x-10.5 ?

OpenStudy (hugsnotughs):

OH! Yes, you are correct! Sorry, I was confused. /.-

OpenStudy (hugsnotughs):

REMINDER: Since x = 12, it is not f(x) = 19.5, it is f(12) = 19.5

ah ok thanks
