Answer:
x-2=x
-2=x
+
=x

x= -10
Step-by-step explanation:
Given exponential function
f(x)= 
Where x is the number of years
f(x) is the number of tuna in thousands
To find out when number of tuna is 50 thousand , we plug in 50 for f(x) and solve for x

Divide by 230 on both sides

Take ln on both sides


Divide by ln(0.881) on both sides
x = 
x= 12.04
Year = 1974 + 12.04 = 1986
so in 1986 there will be 50 thousand tuna.
N=0,8,16,24,...; because when n=8k

then n/8 is natural number.
So the smallest value of n is 0.
Follow these rules:
Multiply and divide before adding and subtracting.
(1/4)(1/4) = 1/16, so now we have 1/16 - 1/4 ÷ 1/4 ÷ 1/4 ÷ 1/4
1/4 ÷ 1/4 = 1, so now we have 1/16 - 1 ÷ 1/4 ÷ 1/4
1 ÷ 1/4 = 4, so now we have 1/16 - 4 ÷ 1/4
4 ÷ 1/4 = 16, so now we have 1/16 - 16
1 - 256
and this simplifies to -15 15/16, or ------------
16
