<span>Answer:
year 0 you get 3 * .25^0 = 3 * 1 = 3
year 2 you get 3 * .25^1 = 3 * .25 = .75
year 3 you get 3 * .25^2 = 3 * .0625 = .1875
the numbers are decreasing year after year so you are talking about decay.
b^x increases as x increases if b is greater than 1.
b^x stays the same as x increases if b is equal to 1.
b^x decreases as x increases if b is greater than 0 and less than 1.
x is assumed to be greater than or equal to 0.</span>
There are multiple ways to do this.
The easiest is to just continuously subtract 7 from 65 the numbers of times needed.
But most math teachers will have you use the equation ar^n-1 where a= the first term (65), r=ratio (-7), and n=the term you need (second, fifth, and ninth).
So to solve you just plug your values in as so
AR^n-1
(65)(-7)^2-1(65)(-7)^5-1
(65)(-7)^9-1

Answer:
Given system of equations:

To solve by substitution, equate the equations and solve for x:

Therefore, the x-values of the solution are
and
.
To find the y-values of the solution, substitute the found values of x into the functions:




Therefore, the solutions to the given system of equations are:
and 
Write an equation to model this situation. Then complete the input-output table below; and graph the equation on the coordinate plane provided. If two quantities x and y are directly proportional to one another, (meaning if x is doubled, so is y; if x is tripled, so is y), they show direct variation.
