Answer:

Step-by-step explanation:
<em>The options are not given; however, the question can still be answered.</em>
Given
Direct Proportion:
In 20 minutes, y = 250 bottles
Required
Determine the graph
<em>In the first 20 minutes, y = 250</em>
<em>In the next 20 minutes, y = 250 + 250 = 500</em>
<em>In the next 20 minutes, y = 500 + 250 = 750</em>
<em />
This gives a arithmetic sequence:
250, 500, 750, ........
Next, is to determine the equation of the sequence using;

In this case;




Substitute these values in the above formula;

Hence; the graph that shows the given description is the graph with equation 
Answer:
D
Step-by-step explanation:
Firstly,
≤ or ≥ means closed circle, and
< or > means open circle
Now, let's solve the compound inequality:
x - 1 ≤ 7
x ≤ 8
and
2x ≥ 22
x ≥ 11
This solution means "everything left of 8 (inclusive and closed circle)" and "everything right of 11 (inclusive and closed circle)"
Looking at the choices, D is right.
Well just plug the two points in... y=7 x=2
3(7) + 2= 5
is that true or not?
3(7)
21
21+2= 23
23 is not equal to 5... so no it does not pass through the point (2,7)
