Answer:
No.
Step-by-step explanation:
2:1 and 19:10 are not equivalent.
Simply, because if you divide 9 by any number with the 10, it is not going to stay as a whole number. For example, 19 divided by 2 equals 9.5. 19 divided by 5 equals 3.8. So, no they are not equivalent.

Step-by-step explanation:
Answer:
x = 11.5, y = -5.5.
As an ordered pair this is (11.5, -5.5).
Step-by-step explanation:
2x+4y=1 Multiply this by 3:
3x+5y=7 Multiply this by -2.
6x + 12y = 3
-6x - 10y = -14 Adding these 2 equations:
0 + 2y = -11.
y = -11/2
y = -5.5.
Now plug this into the first equation:
2x + 4(-5.5) = 1
2x = 1 + 22
x = 23/2
x = 11.5.
Answer:
They are all true except for D
Step-by-step explanation:
What they are asking you to do, is take your rectangle and flip it over the top. QR would stay right where it is and line ST would now be on top and line QR would be the bottom. If you can picture that, you can see that all the statements would be true but D.
