Answer:6n-5
This is an arithmetic sequence since there is a common difference between each term. In this case, adding
to the previous term in the sequence gives the next term. In other words,
Formula:A*n=a*1d(n-1)
Answer:
in math volume is the amount of space in a certain 3D object.
Step-by-step explanation:
For instance, a fish tank has 3 feet in length, 1 foot in width and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six.
For this case, we find the equation of the line, for this we look for points where the line passes:
We found the slope:
Thus, the equation of the line is:
We substitute a point to find "b":
Finally:
Now, the domain is given by all the values for which the function is defined.
It is observed that "x" can take any value, that is, it is defined for all real numbers.

Answer:
Step-by-step explanation:
Let the number of hours Nick does the job alone to be x - 3 hours
Hence, in 1 hour, Nick has done 1/x - 3
Together they complete the job in 9 hours
Hence, let's represent the job as 1
9/x + 9/x - 3 = 1
Multiply through by (x)(x-3)
9(x- 3) + 9(x) = 1
9x - 27 + 9x = (x)(x-3)
-27 = x² - 3x
x² - 3x +27 = 0
