Answer:
A familiar situation is: cost of books you pay for versus the quantity of books bought.
Cost of books ($) and quantity of books are directly proportionally related in the situation.
The graph will look like the graph in the attachment below.
A quantity (dependent variable) will change constantly in relation to another quantity (independent variable) if the relation is a proportional relationship.
A familiar situation for example can be the cost you pay for books will be directly proportional or dependent on the number of books you bought.
That is:
Number of books = independent variable
Cost ($) = 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 ($) you pay on the y-axis.
Therefore:
A familiar situation is: cost of books you pay for versus the quantity of books bought.
Cost of books ($) and quantity of books are directly proportionally related in the situation.

Answer:
72
Step-by-step explanation:
RQS + KLM = 180 degrees, because RQS = QLK, and QLK + KLM = 180 degrees (because they are on the same line).
Substitute the values for RQS and KLM:
x-36 + x = 180 -->
2x-36=180 -->
2x = 144 -->
x=72
Answer:
A
Step-by-step explanation:
We can use vertical line test to determine if a relation is a function.
<em>If a vertical line passes the graph at any point only once, then the relation is a function, if there is even 1 line that passes the graph at 2 points, then it is NOT a function.</em>
<em />
The domain is the set of allowed x-values of the function. The range is the set of allowed y-values of the function.
- Looking at the graph, we see that there are a lot of vertical lines that cuts the graph two times. Suppose x=3, x=4, x= 5 etc. So it is not a function.
- As for domain, we see that curve swings from x = -8 to x = 8, so the domain is from -8 to 8.
- As for range, we that the curve stretches all the way from negative infinity to positive infinity, so the range is the set of all real numbers.
Correct answer is A
Check the picture below
notice, the "a" side goes from -2 to 11
and the "b" side goes from 2 down to -4
