4. Simplify: (-z-2w2)(z-2)-1

-z⁻⁵w²

Step-by-step explanation:

(-z⁻²w²){(z⁻²)⁻¹}

simplify each first

{(z⁻²)⁻¹}  = z⁻²⁻¹ =  z⁻³

(-z⁻²w²) z⁻³

-z⁻² z⁻³ w²)

-z⁻²⁺⁽⁻³⁾w²

-z⁻²⁻³w²

-z⁻⁵w²

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

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.
