For the inverse variation equation p = StartFraction 8 Over V EndFraction, what is the value of V when p = one-half?

likoan [24]

Answer:

V=16

Step-by-step explanation:

We are given that an inverse variation

$p=\frac{8}{V}$

We have to find the value of V when p=1/2

To find the value of V we will substitute the value of p

Substitute the value of p

Then, we get

$\frac{1}{2}=\frac{8}{V}$

$\frac{V}{2}=8$

Using multiplication property of equality

$V=8\times 2$

Using multiplication property of equality

$V=16$

Hence, the value of V=16

Which table represents the equation y = -2x + 17?

Alexeev081 [22]

<h3>Answer: Choice A</h3>

Explanation:

Each table has x = 10 in it. Plug this value into the given equation.

y = -2x+17

y = -2*10+17

y = -20+17

y = -3

The input x = 10 leads to the output y = -3. Table A shows this in the middle-most row. So that's why choice A is the answer. The other tables have x = 10 lead to y values that aren't -3 (eg: choice D has x = 10 lead to y = 12), so we can rule them out.
