Two friends, Alison and Bernard, are

walking along two different roads. The

roads can be represented by the lines with

equations y=-*+ 410 and y=-x-100.

Alison is on the first road at the point with

coordinates (0.410) and Bernard is at the

point with coordinates (50 -75).

a Verify that Bernard is on the road with

cquation y=-x-100.

Find the coordinates of the point of

intersection of the two roads.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

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.
