Answer: Yes

Step-by-step explanation: An arithmetic sequence is a sequence that has a common difference. The common difference is the number that is repeatedly added or subtracted to reach the next term in the sequence.

In this sequence, notice that we start with 15. Then, we subtract 2 to reach our next term which is 13. Next, we subtract 2 to get to our next term which is 11. In the same way, we subtract 2 from 11 to reach our next term, 9.

The dot dot dots just mean that this sequence goes on forever so to answer your question, this is indeed an arithmetic sequence.

rjkz [21]

Answer:

2 teams

Step-by-step explanation:

13 divided by 5 is 2.6, but you cannot split a person in half, so it would be two teams with a remainder of three people.

Can someone help me please

Answer:

(4x + 5)(x² + 25)

Step-by-step explanation:

Given

4x³ + 5x² + 100x + 125 ( factor the first/second and third/fourth terms )

= x²(4x + 5) + 25(4x + 5) ← factor out (4x + 5) from each term

= (4x + 5)(x² + 25)

Which equation has only one solution? |x – 5| = –1 |–6 – 2x| = 8 |5x 10| = 10 |–6x 3| = 0
inn [45]

The linear equation which has only one solution would be |–6x + 3| = 0

<h3>What is a linear equation?</h3>

A linear equation is an equation in which the highest power of the variable is always 1. The standard form of a linear equation in one variable is of the form Ax + B = 0.

|x – 5| = –1

The absolute function cannot be equal to the negative. so we cannot solve this absolute function.

|–6 – 2x| = 8

For this absolute function, we make two equations here

-6-2x= 8  and -6-2x= 8. So we will get two solutions for x.

|5x + 10| = 10

For this absolute function, we make two equations here

5x+10= 10 and 5x+10= -10. So we will get two solutions for x

|–6x + 3| = 0

For this absolute function we make two equations

-6x+3=0 and -6x+3=-0.

Both have the same 0 on the right side. So we will get only one solution for x
