Answer: 
Step-by-step explanation:
Given
Propane produced heat energy of 
The volume of the tank is 
The energy produced by this propane tank is

Slope=change in y/change in x
one way is t pick 2 points, (x1,y1) and (x2,y2)
the slope is (y2-y1)/(x2-x1)
pick some points
(8,4) and (8,0)
slope=(0-4)/(8-8)=-4/0=undefined
the slope is undefined
so you could say there is no solpe
answer is D

Step-by-step explanation:
Luis spent $9.50, in which:

Luis bought 10 snacks in all
10 = x + y
-----------------------------------------------------------------------------------------------------------------
You're answer:
x + y = 10
1.25y + 0.50x = 9.50

Answer:
5/9
Step-by-step explanation:
First, find the total number of mL in the drink:
20 + 10 + 15
= 45

Simplify this by dividing the numerator and denominator by 5:
10/45
= 5/9
So, 5/9 is the proportion of the cocktail that is apple juice
