Answer:

Step-by-step explanation:

To be a function, each input value can only go to one output

X has x=0 going to y=4 and y=6

Y has x=6 going to y=-2 and y =15

Z has x=4 going to y=0 and y =3

W is the only one that has each input going to only one output

PLEASE help a girl out! :)What is the actual area of the room?

andrey2020 [161]

Answer:

$=75$ $ft^{2}$

Step-by-step explanation:

Area is found by mulitplying width and height.

$A=7.5(5)\\$

$A=37.5\\$ in

The ratio is 0.5in : 1ft, so if you multiply that ratio to the answer, you should get the answer in feet.

$37.5$ in x $\frac{1ft}{0.5in}$ $=75$ $ft^{2}$

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:

$r = 100000 t + 600000$

Heeeeeeeeeeeelp 50 points

If X > 0 then X must be a positive number. If Y < 0 then Y must be negative. So the quadrant that contains Positive X values and negative Y values will contain the point that you are looking for. This would be the fourth quadrant.
