Answer:
2x+15y=2960
Step-by-step explanation:
Answer:
$542
Step-by-step explanation:
we know that
The equation of a exponential decay function is given by

where
y is the value of the lawnmower
x is the time in years
a is the initial value
r is the rate of change
we have

substitute


For x=5 years

Answer:
27,000
Step-by-step explanation:
We have been given that after a dose of an antibiotic, the number of bacteria decreases. The equation is
models this "decay" situation. We are asked to find the original number of bacteria.
We know that an exponential decay function is in form
, where,
y = Final value,
a = Initial value,
b = Decay factor,
x = Time.
Upon looking at our given equation, we can see that initial value is 27,000, therefore, 27,000 represents the original number of bacteria.
<span>The unit rate is 1 1/2 pounds of chorizo to 1 cup of rice. I found this answer through proportions. To get from 1/2 cups to 1 cup, I multiplied 1/2 * 2, so I did the same for the chorizo. I multiplied 3/4 *2, which gave me 6/4 and which simplifies to 1 1/2 pounds.</span>
