Usually when you see f(x) or as yours is f(6) f with parenthesis is just a fancy way of saying y= so basically you plug six in for the x values of your question
20100 = 16000 * (1.02)^ t
20100/16000 = 1.02^t
1.25625 = 1.02^t
log 1.25625 = t * log 1.02
t = log 1.25625 / log 1.02
= 11.5

Answer:
Step-by-step explanation:
y=9x-1
8x-4y=92
substitute y=9x-1
8x-4(9x-1)=92
8x-36x+4=92
-28x+4=92
-28x=92-4=88
x=88/-28=22/-7 = -3.14
y = 9(-3.14) -1 = -28.26-1 = -29.26
