D is a function because there are no repeated x values
for example b is not a function because we have (0,-7) and (0,-9)
All I can think of is (5,0) (0,5)
Hopefully it helps.
Leftmostcomet can u help me I posted a math question d
Answer:
Box of Popcorn: $3.00
Drink: $2.00
Step-by-step explanation:
If we input the prices into the original problem it would be something like this, (2)3.00 + (3)2.00 = $12.00 (3+3 = 6 and 2 + 2 + 2 = 6 6+6= 12) Or 2x + 3x = $12
And you would do the same thing for the second one.
(3)3.00 + (5)2.00 = $19.00 ( 3 + 3 + 3 = 9 and 2 + 2 + 2 + 2 +2 = 10 10+9= 19) Or 3x + 5x = $19
Sorry if it's incorrect but i hope it helps!
