The variable $x$ varies directly as the square of $y$, and $y$ varies directly as the cube of $z$. If $x$ equals $-16$ when $z$
Kisachek [45]

If x varies directly as y^2, then there is some constant a for which

x=ay^2

Similarly, there is some constant b such that

y=bz^3

Given that x=-16 when z=2, we have

\begin{cases}-16=ay^2\\y=8b\end{cases}\implies-16=a(8b)^2\implies ab^2=-\dfrac14

Now when z=\frac12, we get

\begin{cases}x=ay^2\\y=\frac b8\end{cases}\implies x=a\left(\dfrac b8\right)^2=\dfrac{ab^2}{64}=\dfrac{-\frac14}{64}=\boxed{-\dfrac1{256}}

If you wanted to shift the graph of y = 2x + 5 up, which equation could you use?
maxonik [38]

Answer:

y = 2x + 5+2 graph would shift by 2 unit.

Step-by-step explanation:

Given  : y = 2x + 5 .

To find :If you wanted to shift the graph up what would be equation .

Solution : We have given that y = 2x + 5 .

BY the transformation rule ; if f(x) +k then graph would shift up by k units .

Then to shift the graph of y = 2x + 5 up we need to add something in 5

Like   y = 2x + 5+2

Then graph would shift by 2 unit.

Therefore,   y = 2x + 5+2 graph would shift by 2 unit.
