Answer:
Number of children, x= 400
Number of adults, y = 100
Step-by-step explanation:
Let the number of children be x
Let the number of adults be y
Given : Total number of people, x + y = 500 --------(1)
Total amount collected, 5x + 10y = 3000 ---------(2)
(1) => y = 500 - x
Substitute y in (2) : 5x + 10(500 - x) = 3000
5x + 5000 - 10x = 3000
-5x = 3000 - 5000
-5x = -2000
x = 400
Substitute x in (1) : 400 + y = 500
y = 500 - 400
y = 100
Answer:
The graph has a domain of all real numbers.
The graph has a y-intercept at .
The graph has an x-intercept at .
Step-by-step explanation:
Given: The graph is
The domain of a function is a set of input values for which the function is real and defined.
Thus, the graph has a domain of .
To find the y-intercept: To find the y-intercept, substitute in .
Thus, the y-intercept is
To find the x-intercept: To find the x-intercept, substitute in .
Thus, the x-intercept is
