account b has 2.6% more interest than account a
Answer:
6, 1, 8, -16
Step-by-step explanation:
For each input we divide it by 2 and then add 3 to get the output:
6/2+3=3+3=6
-4/2+3=-2+3=1
For each output we subtract 3 and multiply it by two to get the input:
(7-3)*2=4*2=8
(-5-3)*2=-8*2=-16
Answer:
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.
40x 60 = 2400. so the area could be 2400.
