Answer:

y = 250x

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;

T_n = a + (n - 1)d

In this case;

T_n = y

x = n

a = 250

d = 750 - 500 = 500 - 250 = 250

Substitute these values in the above formula;

y = 250 + (x - 1) * 250

Open Bracket

y = 250 + 250x - 250

Collect Like Terms

y = 250x + 250 - 250

y = 250x

Hence; the graph that shows the given description is the graph with equation y = 250x

Choose the correct description of the graph of the compound inequality: (5 points)
skad [1K]

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.

Does the line 3y + x = 5 pass through the point (2, 7)?
Lubov Fominskaja [6]
 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)
