In 2000, 49 % of the residents in a large city regularly used newspapers for getting news and this has decreased at an average rate of approximately 1.3 % per year since then. find a linear function in slope-intercept form that models this description. the function should model the percentage of residents, upper p left parenthesis x right parenthesis comma who regularly used the news outlet x years after 2000.

The required function is P(x)=-1.3x+49.

Step-by-step explanation:

Let P(x) be the percentage of residents who regularly used the news outlet x years after 2000.

It is given that in 2000, 49 % of the residents in a large city regularly used newspapers for getting news.

Initial percentage of residents who regularly used the news = 49

It has decreased at an average rate of approximately 1.3 % per year since 2000.

It is decreasing by 1.3% so,

The slope intercept form of a line is

                .... (1)

where, m is slope and b is y-intercept or initial value.

Substitute y=P(x), m=-1.3 and b=49% in equation (1).

Therefore, the required function is P(x)=-1.3x+49.

3.73 * 10^7 is the anser for ttm ur welcome < 3

step-by-step explanation:

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
