Is the sequence arithmetic..... if so identify the common difference
const2013 [10]

Answer:

A) Yes, 7

Step-by-step explanation:

The given sequence  An = {13, 20, 27, 34, ...}

Here the first term Ao = 13 and difference between the successive terms is (d) = 7

That is  d = 20  - 13

d = 7

It is an arithmetic sequence. d = 7

Answer: Yes, it is arithmetic sequence and common difference (d) = 7

Thank you.

What is the x-intercept of the line with this equation? <br><br>−5x + <img src="https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D" i
Sonja [21]
The x-intercept is the point on the graph where it crosses the x-axis. It’s also the value of the x-coordinate when y = 0.

To find the x-intercept, set y = 0:

-5x + 1/5(0) = 15

-5x + 0 = 15
-5x = 15

Divide both sides by -5:

x = -3.

Therefore, the x-intercept is (-3, 0).

What property allows you to conclude that 5x+7x=12x
Andrei [34K]
Since both of the numbers have a variable which is x ready to be multiplied, there is no expression leading to the variable therefore you will add normally but you will need to put the missing variable which needs to be multiplied. So overall you can just add and once you get your variable you can be abe to multiply and get your final answer.

Hope this helps
