In 2004, a magazine's circulation was about 1,000,000 readers. In 2014, the magazine had about 2,000,000 readers. Write a linear

Sever21 [200]

Answer:

$m= \frac{r_2 -r_1}{t_2 -t_1}= \frac{2000000-1000000}{14-4}=100000$

And then we can use for example the first point $(t_1, r_1) = (4, 1000000)$ to find the intercept:

$1000000= 100000*4 + b$

$b=600000$

So then the linear model for this case should be:

$r = 100000 t + 600000$

Step-by-step explanation:

For this case we want to find a linear model given by:

$r =mt+b$

Where r = represent the number of readers , t= years after 2000

m = the slope for the model and b the intercept

For this case we can define the following points from the data given:

$(t_1, r_1) = (4, 1000000)$ 4 years after 2000

$(t_2, r_2) = (14, 2000000)$ 14 years after 2000

We can find the slope with the following formula:

$m= \frac{r_2 -r_1}{t_2 -t_1}= \frac{2000000-1000000}{14-4}=100000$

And then we can use for example the first point $(t_1, r_1) = (4, 1000000)$ to find the intercept:

$1000000= 100000*4 + b$

$b=600000$

So then the linear model for this case should be:

$r = 100000 t + 600000$

Answer:

C) 4

Step-by-step explanation:

Replace the variable a with 4 to see if it makes the equation true.

4 + (-7) + 3 = -3 +3

-3 + 3 = 0; thererfore, the number 4 is the proper solution to the equation.
