Answer:
(A:) I created a scatter plot similar to the one i used for mine, this is for the first part of your question
(B:) Positive Association
Step-by-step explanation:
(B:) Why? Because as your x value increases so does your y and it shows this with the data as well.
I had a tough time with this until i actually read through what it was really asking so i hope this helps you
Let the number be x.
Then, the number increased by 3 will be x + 3.
<u>According</u><u> </u><u>to </u><u>question</u><u>,</u>
x(x + 3) = 54
x² + 3x = 54
x² + 3x - 54 = 0
<u>By middle term factorisation</u>,
x² + 9x - 6x - 54 = 0
x(x + 9) - 6(x + 9) = 0
(x + 9)(x - 6) = 0
<u>Equating </u><u>to </u><u>zeroes </u><u>and </u><u>we </u><u>get,</u>
x + 9 = 0
x = -9 (First value)
and,
x - 6 = 0
x = 6 (second value)
