Answer:

linear and y = 2x + 19

Step-by-step explanation:

the x- values increment by 2 and the values of y increment by 4

This indicates a linear relationship exists in the form

y = mx + c ( m is the slope and c the y-intercept )

m = \frac{rise}{run} = \frac{4}{2} = 2

y = 2x + c ← is the partial equation

to find c use any ordered pair from the table

using (- 5, 9 ), then

9 = - 10 + c ⇒ c = 9 + 10 = 19

y = 2x + 19 ← linear equation

As a check

x = - 7 : y = - 14 + 19 = 5 ← correct value of y

x = - 5 : y = - 10 + 19 = 9 ← correct value of y

x = - 3 : y = - 6 + 19 = 13 ← correct value of y

x = - 1 : y = - 2 + 19 = 17 ← correct value of y

The population of Centerville increases each year. The function C(t) = P(1 +r)^t represents the population of centerville at yea
strojnjashka [21]

Answer:

P represents the population in year 0 ⇒ D

Step-by-step explanation:

* Lets explain the exponential growth function

- The exponential growth function is f(x) = a (1 + r)^t, where a is the initial

  amount (at t = 0), (1 + r) is the factor of growth , r is the rate of growth

  in decimal ant is the time of growth

* Lets solve the problem

∵ The function C(t) = P(1 + r)^t represents the population of

  centerville at year t, where P is the initial population and r is the

  rate of increase

- Ex: If your investment is increased 10% annually, then that means

 each year, your total has multiplied itself by 110% (the growth factor

 is 1 + 10/100 = 1.1)

∴ (1 + r) is the factor grows each year

∵ C(t) = P(1 + r)^t

∴ C depends on P(starting population) , r(the increasing rate and

   t(the time in year)

∵ r is the rate of increase means the percentage of increasing , then

  0 < r < 1

∴ r is not less than 0

∵ P is the initial amount when t = 0

∴ P represents the population in year 0

What can happen if your savings account balance goes below the required minimum daily balance?
Mademuasel [1]

Explanation:

In the banking system, there is a minimum daily balance that is the minimum balance that a banking organisation requires account holders to have in their accounts each day in order to waive off the maintenance fees.  

You need to check with your bank for the requirements of your bank.

If for an instance $500 is the minimum daily balance, <em>it means your account should never go below that amount, not even for a day, or you will have to pay a maintenance fee.</em>

The bank wants to make more money from your deposits in the savings account than you cost them to maintain your accounts.
