Answer:

(0,3)

Step-by-step explanation:

7x-2y=-6  

8x+y=3

Multiply the second equation by 2 so we can eliminate y

2(8x+2y) = 2*3

16x+2y=6

Add the first equation to the modified second equation

7x-2y=-6  

16x+2y=6

--------------------

23x = 0

Divide by 23

23x/23 = 0/23

x =0

Now we need to find y

8x+y = 3

0+y =3

y=3

(0,3)

Carmen drew line A and line B in the two scatter plots shown. one scatter plot contains 12 points indicating a negative correlat
blondinia [14]

The true statement is that only line A is a well-placed line of best fit

<h3>How to determine the true statement?</h3>

The scatter plots are not given. However, the question can still be answered

The features of the given lines of best fits are:

<u>Line A</u>

  • 12 points in total
  • Negative correlation
  • Passes through the 12 points with 6 on either sides

<u>Line B</u>

  • 12 points in total
  • Positive correlation
  • Passes through the 12 points with 8 and 4 in either sides

For a line of best fit to be well-placed, the line must divide the points on the scatter plot equally.

From the given features, we can see that line A can be considered as a good line of best fit, because it divides the points on the scatter plot equally.

Answer:

keiko- x

imelda- x+ 36

Sarah- x- 38

Step-by-step explanation:

  1. keiko is x since we have not been given his number of boxes.
  2. because imelda's number of boxes was 36 <em>more </em><em>than </em>keiko's, you will add the x which is for keiko and 36 for imelda(x+36).
  3. and sarah's number of boxes will be x-36 because we have been told her number of boxes is 38 <em>fewer </em><em>than </em> keiko's.

1/4x + 1 + 3/4c - 2/3 - 1/2x<br><br> what is it equal to??
mylen [45]

Answer: -1/4x+1/3+3/4c

Step-by-step explanation:

<h2>We can't solve it but we can simplify</h2>
  1. 1/4x+1+3/4c-2/3-1/2x, try to move the equation around. Since the operations are in the same level we can do that.
  2. 1/4x-1/2x+(1-2/3)+(3/4c), 1/4 minus 1/2 can be written as 0.25-0.50 which is -0.25 or -1/4 don't forget to add x (we can do this since there like terms)
  3. -1/4x+(1-2/3)+(3/4c), now we can convert 1 into a fraction which will become 3/3, so we can rewrite is as 3/3-2/3, which is 1/3
  4. -1/4x+1/3+3/4c, We can't simplify anymore so this is our final answer.
