Answer:
256
Step-by-step explanation:
4(7)^2 + 30(2)
196 + 60 = 256
First subtract 8.5 from both sides, then divide the -1.2 to get x by itself
x=1.5
Watch closely. I'll try to go slow.
Stop me if I go too fast, or if I do anything that you don't understand.
Ready ?
You said d = r t
Divide each side by ' t ' : d / t = r
The inverse is (x-2)/3 so the answer is f(x)=0
