Answer:
It's simple.
Step-by-step explanation:
Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.
Answer:
49>20
Step-by-step explanation:
12.6 + 31 + 5.4 = 49 >20
The given model would make the least sense to use for x=-2.75.
the given function is:

a quadratic relationship,
where
h is the height in feet
x is the time in seconds
<h3>what is kinetic energy?</h3>
Kinetic energy is a form of energy that an object or a particle has by reason of its motion.
as we know that time always appears to run forward, never backward. cannot take negative values so option 1 i.e 2.75 is not possible. Also, after a certain period of time object will vanish all its kinetic energy, resulting in h=0 but h(-2.75)= -21 which is meaningless.
h(-2.75) = 
h(0.25) = 

h(1.75) = 
h(25) = 
therefore, x=-2.75 this model would make the least sense to use

L = A - 75
C = L + 38
C = 200
200 = L + 38
200 - 38 = L
162 = L
L = A - 75
162 = A - 75
162 + 75 = A
237 = A <====
