Answer:

Step-by-step explanation:
The relationship between A, the area of the glacier in square kilometers, and t, the number of years the glacier has been melting, is modeled by the equation.:

We want to determine the value of t for which the area, A(t)=15 square kilometers.

Therefore, the time for which the area will be 15 sqyare kilometers is:
-20 ln(1/3) years.
B
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = 5x + 3 is in this form with slope m = 5
To decrease the slope we require a smaller, positive value for m
y = x + 3 has m = 1 which is less than 5 and positive
y = x + 3 is less steep than y = 5x + 3
