Answer:

5x - 11y - 6z

Step-by-step explanation:

Subtract common terms (terms with the same variable & same number of variables)

5x - 8y - 12z

-   (+ 3y - 6z)

------------------

5x - 11y - 6z

Remember to distribute the negative sign to all terms within the second expression. Multiply -1 to all terms:

-1(3y) = - 3y

-1(-6z) = 6z

Combine the terms:

-8y - 3y = -11y

-12z + 6z = -6z

5x - 11y - 6z is your answer.

Help please:Suppose that x and y inversely, and x=10 when y=8 write the function that models the inverse variation
jarptica [38.1K]

SOLUTION

From the question, we are told that y varies inversely as x

This is mathematically written as

\begin{gathered} y\propto\frac{1}{x} \\ \propto\text{ is a sign of proportionality } \end{gathered}

Now, we will remove the proportionality sign and replace it with equal to sign =

If we do this, we will intoduce a constant k

\begin{gathered} y\propto\frac{1}{x} \\ y=k\times\frac{1}{x} \\ y=\frac{k}{x} \end{gathered}

So we have the formula

y=\frac{k}{x}

We will substitute the values of x for 10 and y for 8 into the formula to get k, we have

\begin{gathered} y=\frac{k}{x} \\ 8=\frac{k}{10} \\ k=8\times10 \\ k=80 \end{gathered}

Now, we will substitute k for 80 back into the formula to get the inverse function, we have

\begin{gathered} y=\frac{k}{x} \\ y=\frac{80}{x} \end{gathered}

Hence the answer is option C
