ANSWER
One real root.
EXPLANATION
The graph of the function

is shown in the attachment.
According to the Fundamental Theorem of Algebra, this function must have 3 roots including real and complex roots.
The x-intercepts gives the number of real roots.
Observe that the graph has only one intercept.
This implies that, the equation:

has only one real solution.
Answer:
y = 28
Step-by-step explanation:
As I interpret your post, you want to solve
y
---- - 3 = 4 for y.
4
First, add 3 to both sides: y/4 = 7.
Next, mult. both sides by 4 to eliminate the fraction: y = 28.
Answer:
About 108 times
Step-by-step explanation:
Given:
An average soccer player travels 7 miles during a game
A typical field is 104 meters long.
To find:
How many times did the average soccer play travel the length of the field?
Solution:
An average soccer player travels during the game = 7 miles
First convert 7 miles into meters, 1 mile = 1609.34 meter
7 mile = 1609.34 \times 7 = 11265.41 m
Length of field = 104 meters
To find number of times average soccer player travel the length of the field, we will divide an average soccer player travels during the game by Length of field
11265.41 m
104 = 108.32
Therefore, about 108 times average soccer player travel the length of the field
