Step-by-step explanation:
Given,
y = - 10x + 25
To find, the total number of solutions = ?
∴ y = - 10x + 25
⇒ y = - 2(x)(5) +
⇒ y =
There are infinite solution of y.
Thus, there are infinite solution of y.
Answer:
Find out the what function equation represents the population of the city after t years .
To prove
The population of a city is 451,400. The population is expected to decrease at a rate of 3.2% each year.
This can be represented by exponential decreasing function.
Where a is the initial value.
r is the rate in decimal form
t is the time.
Here
a = 451,400
3.2 % is written in the decimal form.
= 0.032
Put in the formula
Therefore the decrease in the population of the city after t years is represented by
