x=3 is your answer. This is because it only crosses the x-axis and this occurs at positive 3. y=3 on the other hand would be a horizontal line that only touches positive 3 on the y-axis.

Does the data in the table represent a direct variation or an inverse variation? Write an equation to model the data in the tabl

MakcuM [25]

The equation for the direct variation is y= kx (where k is contant of variation.)

This equation represent that if x will increase then y will also increase because it's k times x.

Where the equation for indirect variation is $y=\frac{1}{k} x$

By this equation if x will increase then y will decrease and vice versa.

The given data is :

x: 2 4 8 12

y: 4 2 1 2/3

Notice as x is increasing then y is decreasing. Like x has increased from 2 to 4 then y is decresing from 4 to 2 and so on.

So, the given data represent an indirect variation.

Which of the following statements are true

Kobotan [32]

Answer:

Step-by-step explanation:

The answer for this is

See the red line in the graph which says f(X)

See the blue line in the graph which says g(X)

So these are the variables which come under the example of exponential functions

And the answer is option B. Both graphs are exponential functions.

Show that sin (x + pi) = -sin x.

Lunna [17]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

$sin(A + B) = sin A cos B + cos A sin B$

In this problem we have

$sin(x + \pi)=sin (x)cos(\pi) + cos(x)sin(\pi)$

Remember that

$sin(\pi) = 0$

$cos(\pi) = -1$

substitute

$sin(x + \pi) = sin(x)(-1) + cos(x)(0)$

$sin(x + \pi) = -sin(x)$
