Answer:
80%
Convert fraction (ratio) 48 / 60 Answer: 80%
For this case we have that by definition, the discriminant of a quadratic expression is given by:

If the discriminant is less than zero then the expression has two different complex roots.
In this case we have the following expression:

So we have to:

The discriminant is given by:

Then, if we want two complex roots it must be fulfilled that:

Thus, the expression has two complex roots for all values greater than 4.

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.

idk either sorry but
Step-by-step explanation:
I think you need a protractor to help you find the other angles to find x
Answer:22
x-10=12
x= 10+12
x=22
