6a-4 = 3a+54
3a = 58
a = 58/3
a= 19.333
Number of subscriber the magazine will have after 3 years from now approximately be 8767
<u>Solution:</u>
Given that magazine currently has 8700 subscribers for its online web version

After 3 years, time(t) = 36 month
Total number of subscribers after 3 years from now
:
Substitute "t" = 36

Subscribers remaining = 0.12 x 560 = 67.2
The magazine currently has 8700 subscribers
Added Subscriber = 8700 + 560 = 9260
Remaining Subscriber = 8700 + 67.2 = 8767.2
Therefore number of subscriber the magazine will have after 3 years from now approximately be 8767
F^1(-2) = 2(-2) = -4
f(-4) = 1/2 * -4 = -2
f(f^-1(x)) = x so answer is -2
You would have to do distribution you would do 5(2x) which would give you 10 and 5(10) which gives you 50 so your equation would be -60=10x+50 then you would subtract 50 from both sides which would give you -110 your equation would be -110=10x divided 10 on both sides and your answer would be x=-11
