when you got a variable that is x it stays the same it becomes a invisible 1
multiply 12 by 9 the answer is 108
x=108
Answer:
(a) 100 fishes
(b) t = 10: 483 fishes
t = 20: 999 fishes
t = 30: 1168 fishes
(c)

Step-by-step explanation:
Given


Solving (a): Fishes at t = 0
This gives:






Solving (a): Fishes at t = 10, 20, 30






Solving (c): 
In (b) above.
Notice that as t increases from 10 to 20 to 30, the values of
decreases
This implies that:

So:
The value of P(t) for large values is:




Answer:
C and D
Step-by-step explanation:
the answers are C and D.
Answer:
Look below
Step-by-step explanation:
To verify that the solution is (3,4) we can plug the numbers back into the equation.
Remember that the solution to a linear equation is represented in the form (x,y). Therefore we plug 3 in for x and 4 in for y.
4=3+1
4=4 Correct!
Now we need to check the second equation
4=-2(3)+10
4=-6+10
4=4 Correct!
Therefore the solution is (3,4)
