Answer:
x = lillies
y = tulips
x + y = 13
1.25x + .90y = 14.85
-1.25x - 1.25y = -16.25
1.25x + .90y = 14.85
-0.35y = -1.40
y = 4 tulips
x + 4 = 13
x = 9 lillies
(9 lillies, 4 tulips)
Step-by-step explanation:
Answer:
Formulate
Based on the given conditions, formulate:

Evaluate
Evaluate the equation/expression:
20.78461
SO THE ANSWER IS 20.78461
1/2- 3/6 5/10 50/100
3/9- 2/6 1/3
5/7- 10/14 20/28
For something to be a function, the input (x value) can ONLY HAVE ONE output (y value), so if x has multiple outputs, it is not a function
B is not a function because x = 2 and x = 9 has 2 outputs
Your answer is A
