Answer:
im really not to sure on this one. sorry dude
Step-by-step explanation:
the correct domain oh h is C
2x+7y=4
+(-2x-8y=-2)
------------------
0x-y=2
-y=2 (this is the result of adding the two equations)
But...
y=-2
2x+7(-2)=4
x=9
Range is the area of variation between the highest and lowest values, basically the highest value - the lowest value a low range would indicate that the variation is minimal thus that the measurement tool is accurate.
Good luck, hope this helps.
