The <em><u>correct answer</u></em> is:

Any equation that is a multiple of y=3x-1.

Explanation:

In order to graph as the same line, the equations must be the same.  This means that all pieces of the first equation must be multiplied by the same factor, or the equation must be rewritten.

Simplify using the vertical method. (3k + 4)(3k^2 – 5k – 3)
liubo4ka [24]

Answer:

9k^{3} -3k^{2}-29k-12

Step-by-step explanation:

Step 1: Expand by distributing sum groups.

3k(3k^{2} -5k-3)+4(3k^{2} -5k-3)

Step 2: Expand by distributing terms.

9k^{3} -15k^{2} -9k+4(3k^{2} -5k-3)

Step 3: Expand by distributing terms.

9k^{3}-15k^{2} -9k+12k^{2} -20k-12

Step 4: Collect like terms.

9k^{3}+(-15k^{2}  +12k^{2} )+(-9k-20k)-12

Step 5: Simplify.

9k^{3} -3k^{2}-29k-12

Katen [24]
This would be set up as: 6/   = 25/100
so we have to cross multiply 6*100= 600 then 600 divided by 25= 24
Therefore 24 is the answer.

How do i find the proportionality of r
Paha777 [63]
Since the graph is a linear function, we're going to use the slope formula solve this: 

Note I am replacing m with k
k= \frac{ y_{2}- y_{1} }{ x_{2}- x_{1} }

Inserting 2 points from the graph, let's use (1,8) and (2,16).

\frac{16-8}{2-1}&#10;&#10;

k=8
