Put the coordinates of the points (1, 21) and (2, 6) to the equation of the function:
Substitute (*) to (**):
Put the value of a to (*):
Answer:
If you trace your finger along the line, the points at where your finger increase and decrease along the y axis are these intervals. Interval notation is useful because it states starting points and end points. The first number is the min, and the second is the max number.
Decreasing:
[-8,-5)
[4,8)
Increasing:
(-5,0]
And? What happens to her and the calculator?

divide 80 by 4 to get 20
20 - 14 = 6
6 is the answer
Okay so let’s say the permit fish is the variable p.
The tarpon is 11p.
So, to set up the equation,
(11p)+p=168
Start by combining like terms on the left
12p=168
Divide both sides by 12 to isolate p
p=14
So therefore, the permit fish was 14 pounds.
To find the weight of the tarpon, insert the 14 back into (11p) 11(14)=154.
You can check by adding these together 14+154=168
So:
The permit fish weighed 14 pounds.
The tarpon weighed 154 pounds.
Hope this helps!
