Answer:

  D.  5 +6k/n

Step-by-step explanation:

The width of the interval is (5 -2) = 3. The width of one of n parts of it will be ...

  3/n

Then the difference between the left end point of the interval and the value of  x at the right end of the k-th rectangle will be ...

  k·(3/n) = 3k/n

So, the value of x at that point is that difference added to the interval's left end:

  2 + 3k/n

The value of the function for this value of x is ...

  f(2 +3k/n) = 2(2 +3k/n) +1 = (4 +6k/n) +1

  = 5 +6k/n

Which equation best represents the relationship between x and y in the graph? (PLEASE ANSWER I BEG YOU :( PLSSSSS)​
USPshnik [31]

Step-by-step explanation:

We observe the line graph.

For every 1 block across, the line goes up by 2 blocks. Therefore Slope = Rise/Run = (2)/(1) = 2.

Also, the y-intercept when x = 0 is 2.

Slope-intercept form: y = mx + c

Hence we have y = 2x + 2. (C)

What goes in the space? (3x − ...)2 = 9x2−6x+1<br> I will give points and brainliest!
Crazy boy [7]

{(x - y)}^{2}  =  {x}^{2}  - 2xy +  {y}^{2}

(3x - ...)^{2}  = 9 {x}^{2}  - 6x + 1 \\  {(3x - 1)}^{2}  = 9 {x}^{2}  -6x + 1
