<em><u>13 and 5</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>Step-by-step explanation:</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>x+y=18</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>x-y=8</u></em>
<em><u></u></em>

<em><u>_____</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>2x=26</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>x=13</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>So the first number must be 13</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>13+y=18</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>y=5</u></em>
<em><u></u></em>
<em><u></u></em>
<u><em>And the second number must be 5</em></u>
Answer:
A). y > x – 2 and y < x + 1
Step-by-step explanation:
Personally I used desmos in algebra it gives you the visual representation x=
Elimination would be the best
Here is an example:
Find the MAD of 2,4,6,8 Step 1 : Find the mean of the data : (2+4+6+8) / 4 = 20/5 = 4 Step 2 : Find the distance between each data and mean. Distance between 2 and 5 is 3 Distance between 4 and 5 is 1 Distance between 6 and 5 is 1 Distance between 8 and 5 is 3
Step 3 : Add all the distances : 3+1+1+3 = 8
Step 4 : Divide it by the number of data : 8 / 4 = 2 2 is the average absolute deviation.
