The function
gives the number of the original trout alive after x years. When the number of the original trout alive is 300, then

Solve this equation:

Answer: after 4.024 year (or 5 year if round to the whole number of years)
57/6 = 1/x
57 = 6x
x = 0.11 miles per minute
Answer:
y=-2x+b
Step-by-step explanation:
Just use the formula y=ax+b, and input -2 as A, and 3, as x, and 2, as y, and then simplify.
answer is 2+ 1/4x + 1 the simplest form is x= -3/4 or -0.75
