The sequence is to take the previous number and multiply by 4, so the sequence is

3 12 48 192 768 3072 12288

add them all up and you get 16383

Answer:

3, 12, 48, 192, 768, 3072, 12288 these are the next seven numbers

Add them all up and you get

<h2>= 16383 Answer C</h2>

Step-by-step explanation:

3, 12, 48, 192

So from 3 to 12 is multiply by 4

So we have checked that it works for all of them

Rule:

Each term is: Two to the power of the number3/4 times the number squared plus 0 times the number

I hope this has helped :)

Which equation represents a line which is perpendicular to the line y = -x + 8?
natima [27]

Two lines are perpendicular between each other if their slopes fulfills the following property

m_1m_2=-1

where m1 and m2 represents the slopes of line 1 an 2, respectively.

To find the slope of a line we can write it in the form slope-intercept form

y=mx+b

Our original line is

y=-\frac{1}{8}x+8

Then its slope is

m_1=-\frac{1}{8}

Now we have to find the slope of the second line. Using the first property,

\begin{gathered} m_1m_2=-1_{} \\ -\frac{1}{8}m_2=-1_{} \\ m_2=(-1)(-8) \\ m_2=8 \end{gathered}

Then the second line has to have a slope of 8.

The options given to us are:

\begin{gathered} x+8y=8 \\ x-8y=-56 \\ 8x+y=5 \\ y-8x=4 \end{gathered}

Then we have to determine which of these options have a slope of 8. To do that we write them in the slope-intercept form:

\begin{gathered} x+8y=8\rightarrow y=-\frac{1}{8}x+1 \\ x-8y=-56\rightarrow y=\frac{1}{8}x+7 \\ 8x+y=5\rightarrow y=-8x+5 \\ y-8x=4\rightarrow y=8x+4 \end{gathered}

Once we have the options in the right form, we note that the only one of them that has a slope of 8 is the last one.

Then the line perpendicular to the original one is

y-8x=4
