<h2>Answers: D, B.</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2>

<em>Explanation for B: </em><u><em>Negative numbers are on the </em></u><u><em>LEFT side</em></u><em> of the number line.</em>

<u><em>And positive numbers are on the </em></u><u><em>right</em></u><em>.</em>

<em>Therefore, </em><em>9 is to the RIGHT of -9 </em><em>on the numberline.</em>

Answer: Hi!

Answers B and D are correct.

For B, since negative numbers are on the left side of the number line, a positive number would have to be to the right of a negative number. Since we are adding a negative and a positive number of the same absolute value (9), they would cancel out to 0, which makes D true.

Hope this helps!

Write the equation of the line in slope-intercept form using y=mx+b​
AnnZ [28]
It looks like it goes through (0,-3) and (1,2), so the gradient is (change in y)/(change in x) ->
(-3-2)/(0-1) = 5
So y=5x+b

Then as we know it passes the y axis at (0,-3) so b= -3

So we have y=5x-3

Box and whisker plots please help!
kotykmax [81]
The correct answer is D. 100%
Each tick counts as 8 so the beginning of the plot would be at 28 which is only 2 from 30 and everything else is on the plot is greater than 30 so the answer would have to be D since 75% would be too little coverage of the plot

Ethan bought 4 packages of pencils. After he gave 8 pencils to his friends, he had 40 pencils
LiRa [457]

He had 40 pencils left after he gave away 8, so originally he had 40 + 8 pencils, which is 48.

Now, he bought 4 packages, which had a total of 48 pencils, so divide 48 by 4, which is 12. He had 12 pencils in each package.

To determine the solution arithmetically, first add 8 to 40, then divide 48 by 4.

To determine the solution algebraically, set up and solve the equation 40 = 4x - 8.

Each package contained 12 pencils.

Hope this helps

Answer:

22/29

Step-by-step explanation:

Add up all the eight grade student that participated in this survey which is 29.

Then add all the eight grade students that do not play guitar which is 22. So 22/29 is the amount of students that play an instrument other than a guitar in fraction form.

Hopefully you got the correct answer. Let me know if you got it wrong.
