A blue whale is swimming at an average rate of 3 miles per hour. Write a linear equation that gives the distance y in miles that the whale swims in x hours.

y = 3x

Step-by-step explanation:

you can use the equation to determine how many miles the whale swims in any desired hour

example, if you want to know how far it swims in 5 1/2 hours then just plug 5 1/2 in for 'x' and solve for 'y'

y = 3(5.5)

y = 16.5

whale travels 16.5 miles when going at a rate of 3 mph

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
