Answer:
y=1.5x
Step-by-step explanation:
Use the equation y-y1=m(x-x1)
y-9=1.5(x-6)
y-9=1.5x-9
y=1.5x
The rate of change is 4 so your answer would be D. 4
Answer:
The function
is represented by
.
Step-by-step explanation:
Statement indicates that atmospheric pressure decreases exponentially when height above sea level is increased. This fact is represented by the following model:
(Eq. 1)
Where:
- Atmospheric pressure at sea level, measured in kilopascals.
-Atmospheric pressure decrease rate, dimensionless.
- Height above sea level, measured in kilometers.
- Current pressure, measured in kilopascals.
If we know that
and
, the function
is represented by:

Answer:
hope this helps
Step-by-step explanation:
y=2x
y=-2x-4
2x+2x=-4 (grouping like terms)
4x=-4
x=-1
im sorry but im not sure what y is
