A familiar situation is: <em><u>cost </u></em><em><u>of books you pay for versus the </u></em><em><u>quantity </u></em><em><u>of books bought.</u></em>
Cost of books ($) and quantity of books are directly proportionally related in the situation.
The graph will look like the graph in the <em>attachment </em>below.
A quantity (dependent variable) will change constantly in relation to another quantity (independent variable) if the relation is a proportional relationship.
- A familiar situation for example can be the cost you pay for books will be directly proportional or dependent on the number of books you bought.
That is:
- Number of books = independent variable
- Cost ($) = dependent variable
- A change in the number of books will cause a change in the cost you will pay for buying books.
This shows a direct proportional relationship between the two quantities.
On a straight line graph, the graph will be a proportional graph showing number of books on the x-axis against cost ($) you pay on the y-axis.
<em>Therefore:</em>
- A familiar situation is: <em><u>cost </u></em><em><u>of books you pay for versus the </u></em><em><u>quantity </u></em><em><u>of books bought.</u></em>

- Cost of books ($) and quantity of books are directly proportionally related in the situation.
- The graph will look like the graph in the <em>attachment </em>below.

<h3>
Answer: 103</h3>
Explanation:
The term "bisect" means "divide in half", or "divide in two equal pieces".
Angles A = 58 and B = 96 divide in half to get 29 and 48 respectively
Find their sum and subtract it from 180 to get angle AMB
29+48 = 77
180-77 = 103

Answer: 32 room
Step-by-step explanation:

<u>If 1 room = 7.75 yd of carpet ⇒ x rooms = 250 yd of carpet</u>
Use proportions & cross-multiply to solve:

So 250 yd of carpet can cover about 32 rooms.
Which of the sets of ordered pairs represents a function? A = {(1, -2), (3, -5), (5, 2), (7,5)} B = {(4, 2), (4, -2), (9,3), (9,

Answer: only A
all of A’s inputs are different but B’s repeats 4 and 9 making it not a function, so its only A
