1÷2(2x+6)=4x-1

solve pls no links!!!​

Step-by-step explanation:

1 ÷ 2(2x+6) = 4x-1

1 = (4x - 1)(4x + 12)

Use FOIL method.

1 = 4x * 4x  + 4x *12 - 1 * 4x - 1*12

1 = 16x² + 48x - 4x - 12

1 = 16x² + 44x -12

0 = 16x² + 44x - 12

16x² + 44x - 12 = 0

Divide the whole equation by 4

4x² + 11x - 3 = 0

4x² + 12x - 1x -3 = 0

4x(x + 3) - (x + 3) = 0

(x + 3)(4x - 1) = 0

x + 3 = 0          ; 4x -1 = 0

    x = -3           ; 4x   = 1

                            x = 1/4

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

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.
