The bottom right graph is correct. x must fall between 3 and 6, so that automatically rules out the bottom left, as one of the points falls on 2.
the top left is incorrect because it doesn't show that x is greater than or EQUAL to three. it has an open circle rather than a closed circle. that's two answer choices eliminated.
from there, you just have to refer back to your given information:
<span>3≤x≤6
the given info says that x must be between or equal to 3 and 6. the top right graph leaves out a "step" because it has 5 and 6 as solid dots side by side.</span>
0.325
Hope that helps you out Summerhazelwood! :D
<h3>hello!</h3>
the "sum of" means we add.
So the sum of n and 12 means we add n and 12:-
n+12
or
12+n (both of these expressions mean the same thing)
<h3>note:-</h3>
Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I'll comment and/or edit my answer :)
