Find the 6th term of the arithmetic sequence X – 9, -X – 11, -3.3 – 13, ...
MrMuchimi

Answer:

-13x-23

Step-by-step explanation:

Given sequence:  x-9, -x-11, -3x-13

Therefore,

  • a_1=x-9
  • a_2=-x-11
  • a_3=-3x-13

General form of an arithmetic sequence: a_n=a+(n-1)d

(where a is the first term and d is the common difference)

To find the common difference, subtract a term from the next term:

\begin{aligned}d & =a_2-a_1\\ & =(-x-11)-(x-9)\\ & = -x-11-x+9\\ & = -2x-2\end{aligned}

Therefore,

a_n & =(x-9)+(n-1)(-2x-2)

To find the 6th term, input n = 6 into the equation:

\begin{aligned}\implies a_6 & =(x-9)+(6-1)(-2x-2)\\ & = (x-9)+7(-2x-2)\\ & = x-9-14x-14\\ & = -13x-23\end{aligned}

Determine the slope of the line that contains the given points <br><br> J(-5, -2), K(5, −4)
Irina-Kira [14]

Answer:

-\frac15

Step-by-step explanation:

Hello!

We can utilize the slope formula to find the slope.

Slope Formula: S = \frac{y_2-y_1}{x_2-x_1}

Remember that a coordinate is written in the form (x,y)

<h3>Find the Slope</h3>
  • S = \frac{y_2-y_1}{x_2-x_1}
  • S = \frac{-4-(-2)}{5-(-5)}
  • S = \frac{-2}{10}
  • S = -\frac15

The slope of the line is -\frac15.
