{X-5-12 Which statement explains why the two systems of equations below have the same

solution?

6x +y = -10

12x+16--20

A. The first equation in B is the sum of the equations in A, while the other is obtained

by multiplying the second equation in A by 6.

B. The first equation in D is the sum of the equations in A, while the other is obtained

by multiplying the first equation in A by 2.

C. The equations in A are increased by 12 and -92 to get the equations in B.

D. The first equation in D is the difference of the equations in A, while the other is

bbtained by multiplying the first equation in A by-2

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

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.
