Select all the statements that correctly describe
the solutions to this system of equations.
2x - y = 0
x + y = 9

A. There is exactly one solution to the system of
equations.

B. There is more than one solution to the system of
equations.

C. The coordinates (3,6) are the solution to the
system of equations.

D. The coordinates (6,3) are the solution to the
system of equations.

E. The coordinates (-3, -6) are the solution to the
system of equations.

B,C

Step-by-step explanation:

System of equations always has more than 1 solution or undefined so B

2x - (-x +9) = 0

y= -x +9

2x + x - 9=0

y= -x +9

3x = 9

y= -x +9

x=3

y= -3+9 = 6

So C is also the right answer

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
