a student studying marine biology created a model. for the population of fish in a nearby lake where the population decreased 25% over a year she ised the model P=714(0.75)^y where P is the population y years afyer 2020 write a model that would predict the population after m months

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21

your answer is no

step-by-step explanation:

the meatpacking industry was most affected by the refrigeration railcar.

any line whose slope not equal to -4 does not satisfy these requirements.

step-by-step explanation:

going from (1,2) to (3, -6), x increases by 2 and y decreases by 8.   thus, the slope of a line thru those two points has the slope m = -8/2, or   m = -4.

thus, no line that has a slope different from m = -4 could be appropriate.
