<span>Here is a step by step process of how to do the paper and pencil solution:1.  Prepare a scatter plot of the data on graph paper.2.  Using a strand of spaghetti, position the spaghetti so that the plotted points are as close to the strand as possible.

3.  Find two points that you think will be on the "best-fit" line.  

<span>4.  </span>We are choosing the points (9, 260) and (30, 530).  
You may choose different points. 5.  Calculate the slope of the line through your two points (rounded to three decimal places).6.  Write the equation of the line. 7.  This equation can now be used to predict information that was not plotted in the scatter plot.

I don't know what I am doing help please (C:
NeX [460]

Answer:

Step-by-step explanation:

The far right side of the triangle is 17 cm, which is the height.

The base would be 34 minus 17 because whole length of the rectangle is 34 and the triangle covers all but 17 of it.

So then you would take 1/2 of 17.

Then multiply it by 17 to get 160.5

If f(x)=x/3 -2 and g(x)=3x^2+2x-6 find (f+g)(x)
umka21 [38]

Answer:

(f + g)(x) = 3x² + (7/3)x - 8

Step-by-step explanation:

To find (f + g)(x), you need to add both the f(x) and g(x) equations together.

f(x) = x/3 - 2 ..... which is equal to ... f(x) = (1/3)x - 2

g(x) = 3x² + 2x - 6

(f + g)(x) = ((1/3)x - 2) + (3x² + 2x - 6)          <----- Add both equations

(f + g)(x) = 3x² + (1/3)x + 2x - 2 - 6              <----- Rearrange (2 = 6/3)

(f + g)(x) = 3x² + (7/3)x - 8                           <----- Simplify similar terms
