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

Which Of the following is the solution to 4|x+3|>8?
Shalnov [3]
Too bad you haven't shared illustrations of the possible solutions.

Starting with   4|x+3|>8, div. both sides by 4:     <span>|x+3|>2

Case 1:  x+3 is already positive:  then x+3>2, or x > -1

Case 2:  x+3 is negative:  Then -(x+3)>2, or -x - 3 > 2, or -5>x or x<-5

Draw a number line representing x values.  Place empty circles at x = -5 and x = -1.  Draw a vector from the circle at x = -1, to the right of x = -1.  Draw a vector from the circle at x = - 5, to the left of x = -5.  Note that x values between x = -5 and x = -1 are not solutions.</span>

The blueprint (a scale drawing used by architects and others) for Zahra’s new office measures `4` cm long and `2` cm wide. The s
Dimas [21]

Using scale concepts, it is found that the length of her office is of 10 ft, while the width is of 5 ft.

------------------------

  • The scale of 6 cm to 15 ft means that each <u>6 cm in the drawing represent 15 ft in actual dimensions</u>.
  • From this, a rule of three is applied to find the dimensions.

First, we find the actual length:

6 cm - 15 ft

4 cm - x ft

6x = 60

x = \frac{60}{6}

x = 10

The actual length is of 10 ft.

Then, we find the actual width:

6 cm - 15 ft

2 cm - x ft

6x = 30

x = \frac{30}{6}

x = 5

The actual width is of 5 ft.
