If you would fill in the blanks, that would really be appreciated!
Triss [41]

Answer:

By applying the slope formula , I find that the slope of segment DE is zero since the difference between the y coordinates  of points D and E  is zero and  any number divided into zero is zero.  The slope of segment AB is also zero  because  (0-0) /(x2-0) =0   Because the two segments have the same slope  they must be parallel  according to the definition of parallel lines.

Step-by-step explanation:

slope formula = (y2-y1)/(x2-x1)

slope for DE = (y1/2-y1/2)/((x1+x2/2 - x1/2)

                      = 0 /(x2/2)

                      = 0


slope for AB = (0-0)/((x1+x2/2 - x1/2)

                      = 0 /(x2-0)

                      = 0/x2

                      =0


Parallel lines have the same slope

What is 3,130,649 rounded to the nearest hundred ?
Readme [11.4K]


When you need to round a number. First you need to look at the placement number that the question is asking to round to the nearest. In this case it's the nearest hundred.

3,130,<u>6</u>49 the 6 is in the hundreds place. Now look to the number to the right of that number 3,130,6<u>4</u>9 that's the number that tells you if you will round up or down. If the number is 5 or more you round up, if it's less than 5 you round down.

In this case the 4 is less than 5 so you round down.

So your answer would be <u>3,130,600</u><u />

Hope this helps. :)

The attached graph represents the graph of the equation 3x + y = 10

<h3>How to determine the line graph?</h3>

The given parameters are:

  • Budget: $10
  • Smoothies: $3
  • Candy bars: $1

Represent the number of smoothies with x and the number of candy bears with y.

So, the equation is:

3x + 1y = 10

This gives

3x + y = 10

Next, we plot the graph of the above equation

See attachment for the graph of 3x + y = 10
