Using the equation 2x + y = 4, we get the following graph.
Step-by-step explanation:
1. d = rt
Divide t from both sides.

2. PV = nRT
Divide P from both sides.

3. 
Add g to both sides.
= g + a
Now multiply by 2 on both sides.
x = 2(g + a)
(or, x = 2g + 2a)
4. g
Divide g from both sides.

Now subtract 1.5 from both sides.
h = 
5.
n = 
The kinetic energy of an object is the energy that it possesses due to its motion.

Answer:
Since we know it is less than, x will be on the left of 1.8. We also know it is not less than or equal to, so the circle is open.
