Answer:
Step-by-step explanation:
Domain of a function is given by the set of x-values (Input values) on the graph.
Range of a function is given by the set of y-values (output values) on the graph.
From the graph attached,
Set of time will represent the "domain" and set of snowfall will represent the "range" of the function graphed.
a). Domain of the function: 0 ≤ x ≤ 5
b). Range of the function: 0 ≤ y ≤ 10

Answer:
7 tenths -> 7/10, that's it
Ok lets say
popcorn = x and
drinks = y
Jacob: 2x + 3y = 18.25
Zachary: 4x + 2y = 27.50
ok now you have to use these 2 equations to get the answer
4x + 2y = 27.50 ---> 2y = 27.50 - 4x ---> y = 13.75 - 2x
2x + 3y = 18.25
2x + 3(13.75-2x) = 18.25
2x + 41.25 - 6x = 18.25
-4x + 41.25 = 18.25
-4x = -23
x = 5.75 <u><em>One bag of popcorn is $5.75</em></u><em />
4x + 2y = 27.50
4(5.75) + 2y = 27.50
23 + 2y = 27.50
2y = 4.50
y = 2.25 <u><em>One drink is $2.25</em></u><em />
