Answer:

  b.  4^-3

Step-by-step explanation:

The expression can be simplified to a number of different levels. Here, it looks like the answer choices want you to simplify it like this:

  \dfrac{8^{-3}}{2^{-3}}=\left(\dfrac{8}{2}\right)^{-3}=\boxed{4^{-3}}

Write an equation parallel to y= -5/2x + 9 that passes through the point (-6,7) brainly
frozen [14]

Answer:

Step-by-step explanation:

If two lines are parallel, that means their slopes are equal.

And we also know that the line must pass through (-6,7)

And with our point-slope equation, we get the equation:

y-7 = -\frac{5}{2} (x+6)

y - 7 = -\frac{5}{2} x-15\\y= -\frac{5}{2} x-8<------ Answer

Hope that helps!
