Assuming you are asking
does -2x+y=6 and y-2x=4 have a solution
look at them
rewrite first equation by switching x and y
y-2x=6 and
y-2x=4
false since they are same values
there is no solution
these 2 lines are paralell
NO SOLUTION
Answer:
1.4%
Step-by-step explanation:
Avery's error was ...
measured - actual = 14.7 in - 14.5 in = 0.2 in
As a fraction of the actual length, that is ...
(0.2 in)/(14.5 in) × 100% ≈ 1.4%
The measurement error was about 1.4%.
Answer:
I believe the answer is D
Step-by-step explanation:
I'm not 100% sure though
The Answer from when you are doing the equation: Negative 8 :The answer to the question:E
Step-by-step explanation: When you add negative numbers, you are basically adding normal numbers, or atleast they look that way, you are actually subtracting but lest just pretend we are adding except they are not normal, all you have to do is add the numbers, but put a negative sign before you put in a number.
C because all you need to do is compare the 2 variables and then add the variables and the multiply it and then divide it. Then your golden.
