Answer:
2 hours 30 minutes
Step-by-step explanation:
210 - 30 = 190
190 / 75 = 2.5
Sorry if I'm wrong.
Fun fact
if f(a)=b then f⁻¹(b)=a
so
if f⁻¹(b)=a then f(a)=b
so we find f(x)=27 and the solve for x
f(x)=3x=27
3x=27
divide both sides by 3
x=9
so if f(9)=27 then f⁻¹(27)=9
problem solved
answer is 9
I wish I can’t help but lol k bye
No idea what language you're talking in, sorry but I only understand English? There is no photo here either.
Please Evaluate?
Thank you.
I think this is the associative property of multiplication.
