A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if:
y=kx
for some constant k , called the constant of proportionality .
(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .")
This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.
Answer:
1188
Step-by-step explanation:
33 X 36 = 1188
TO FIND AREA: Height x width= area
Height is 33 Width is 36
40 is just a distraction! :)
Answer:
$16,748
Step-by-step explanation:
we know that
The equation of a exponential decay function is equal to
where
y is the value of the car
x is the number of years
a is the initial value
r is the rate of change
In this problem we have
substitute
For x=3 years
substitute
