NEED HELP RN!!!!!
Kazeer [188]

Answer:

4(2n-5)

Step-by-step explanation:

So we know Valerie has 5 less than double the number of brad's books. Brad has n books, so make that 2n to double it.

Because she has 5 less than that, the expression is now 2n-5. The is the total of Valerie's books.

We know that Brad has 4 times the number of Valerie's books, so just multiply that expression by 4.

The final answer is 4(2n-5).

You're welcome. :)

Consider the following planes. 3x − 2y + z = 1, 2x + y − 3z = 3
prisoha [69]

Solve for any of the variables; for instance, z:

z=1-3x+2y

z=-\dfrac{3-2x-y}3

Then

1-3x+2y=-\dfrac{3-2x-y}3\implies11x-5y=6\implies\begin{cases}y=\frac{11x-6}5\\z=1-3x+\frac{22x-12}5\end{cases}

Let x=t; then the intersection is given by the vector-valued function

\vec r(t)=\left(t,\dfrac{11t-6}5,1-3t+\dfrac{22t-12}5\right)

or

\vec r(t)=\left(t,\dfrac{11t-6}5,\dfrac{7t-7}5\right)
