Answer:
y=2x+3 is non-proportional. y=5x is proportional.
Step-by-step explanation:
y=2x+3 is not proportional because there is the +3. also, when it is graphed on a graph, the line does not pass through the origin/zero.
y=5x is proportional because it does not have any other values attached to the y value. when it is graphed, the lie goes through the origin/zero.
Answer:
Step-by-step explanation:
(x + 200)20 = 200(10) + x(40)
20x + 4000 = 2000 + 40x
2000 = 20x
X = 100 mL
B is true
