Which statement are true

Ket [755]

Answer:

Line XY contains ray OX and ray OY
Line XY contains segment YX
Ray YX exists in the diagram

Step-by-step explanation:

A ray can be named by any pair of points on an infinite line. Point O, X, and Y on the same line can be used to name rays OX, OY, XY, YX, OY, and XO. The first point named is the end point of the ray. The ray goes through the other point and continues indefinitely.

BA can be the name of a line segment, but not a ray. The line shown does not extend from point B beyond point A.

Any segment can be named by its end points in either order.

So, we have ...

Line XY contains ray OX and ray OY
Line XY contains segment YX
Ray YX exists in the diagram

The correct answer is C and E

Explain

A. 8x+4x=0

Now simply it

12x = 0

Now divide by 12 on both both side

X= 0

So this equation has the solution x= 0

B. 6x+2 = 4x+2+2x

Now both sides

6x+2=6x+2
Now simply by 6x+2 both sides

X= 0

So this equation has infinity solution

C. 4x-8x-3=6-4x

Now simply both sides

-4x-3=6-4x

Now simply

-3x=6

This equation have no solution

D. 5x+1 =1-5x

Now add 5x-1 on both sides

10=0
Now divide by 10

X= 0

This equation have solution x= 0

E. 12x-3-5x = 9+7x-6

Now simply both sides

7x-3= 7x+3

And subtract 7x from both sides

-3 = 3

So the equation has no solution

I hope this help you :D

Good luck
