There is a designated formula for this circle drawing. This is a secant-secant scenario, and in this case, the formula is:

CD(CD+X)=CB(CB+AB)

Plug the values in.
AB=42
BC=18
CD=4

4(4+x)=18(18+42)
Solve for x.
16+4x=1080
4x=1064
x=266
Your answer is C

Answer:

Multiply the first equation by 3 and multiply the second equation by -2.

This is justified by the multiplication property of equality

Step-by-step explanation:

we have

$2x+5y=7$ ----> first equation

$3x+4y=6$ ----> second equation

step 1

Multiple the first equation by 3 both sides

$3(2x+5y)=3(7)$ -----> by multiplication property of equality

$6x+15y=21$ ----> new first equation

step 2

Multiple the second equation by -2 both sides

$-2(3x+4y)=-2(6)$ -----> by multiplication property of equality

$-6x-8y=-12$ ----> new second equation

step 3

Solve the system of equations by elimination

Adds new first equation and new second equation

$6x+15y=21\\-6x-8y=-12\\-------\\15y-8y=21-12\\7y=9\\y=\frac{9}{7}$

Find the value of x

substitute the value of y in any equation and solve for x

$6x+15y=21$

$6x+15(\frac{9}{7})=21$

$6x=21-\frac{135}{7}$

$6x=\frac{12}{7}$

$x=\frac{2}{7}$

The solution is the point $(\frac{2}{7},\frac{9}{7})$

therefore

Multiply the first equation by 3 and multiply the second equation by -2.

This is justified by the multiplication property of equality

How can I<br> arrange<br> this

Anestetic [448]

Answer:

The Independent Variable shall always be the X-Axis

The Dependent Variable shall always be the Y-Axis

The title is up to you!!

See the Screenshot for graph!!

Step-by-step explanation:

First, label the axis whether x or y.

I insist you to do months as the x-axis and the # of deer for the y-axis.

**The y-axis can show differences and variations in the data which is why that is crucial to have the number of deer as the y-axis.**

Now, label the axises meaning you need to use the coordinate to make precise labels! On the y-axis, you need to mark it going up by 5's because the frequency of the data can go up or down 5.

After labeling the y-axis, the x-axis shall have 6 categories which have to have room in order to create a bar graph.

Now, graph! The Screenshot gives a clear definition.

_______________________________________________________

The independent variable is a variable that doesn't depend on another one.

The Dependent is the opposite of the independent.

The independent variable shall always be the X-Axis

The Dependent Variable shall always be the Y-Axis

The title is up to you!!
