Write a statement that correctly describes the relationship between these two sequences: 2, 4, 6, 8, 10 and 1, 2, 3, 4, 5. i rea
madreJ [45]

The first series is an arithmetic sequence with a common difference 2, for the second series is an arithmetic sequence with a common difference 1.

<h3>What is a sequence?</h3>

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

For the first sequence:

2, 4, 6, 8, 10

The above sequence represents the arithmetic sequence

The common difference = 4 -2 = 8 - 6 = 2

For the second series:

1, 2, 3, 4, 5

The above sequence represents the arithmetic sequence

The common difference = 2 -1 = 4 - 3 = 1

Thus, the first series is an arithmetic sequence with a common difference 2, for the second series is an arithmetic sequence with a common difference 1.

Hi good morning can you please help me Write two polynomials whose difference is 6x+3
vaieri [72.5K]

Answer:

9x+8 and 3x+5.

Explanation:

Let the first polynomial = 9x + 8

Let the second polynomial be a+b

\begin{gathered} 9x-a=6x \\ a=9x-6x \\ a=3x \end{gathered}

Similarly:

\begin{gathered} 8-b=3 \\ b=8-3 \\ b=5 \end{gathered}

Thus, the second polynomial = 3x+5

Therefore, the two polynomials whose difference is 6x+3 are 9x+8 and 3x+5.

Write the equation of the line that passes through the points (4,5) &amp; (-3, -1)
klemol [59]

Answer:

y=6/7x+11/7

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-5)/(-3-4)

m=-6/-7

m=6/7

y-y1=m(x-x1)

y-5=6/7(x-4)

y=6/7x-24/7+5

y=6/7x-24/7+35/7

y=6/7x+11/7
