Answer:
C. (1, 1, 2)
Step-by-step explanation:
Well plugging them in one by one.
x + y - z = 0
-1 + 2 - 4 = 0
no.... no it doesn't equal 0 so it isn't the solution
-1 + 0 - 2 = 0
nope it doesn't equal 0 so it's also not the solution
1 + 1 - 2 = 0
Yes! this could equal the solution so lets keep going down the line
3x - y + z = 4
(3*1) -1 + 2 = 4
Yes! this also is correct
I could keep talking and talking but yes, (1, 1, 2) is your answer

The first answer choise
Step-by-step explanation:
x≤−3
So in 10 years, the population will double.
8 years is just before doubling to 6800.
If you consider 10 years to be 100% of the doubling time, 8 years is 80%.
And 80 as a decimal is 80/100 = 0.8
So the answer is 0.8 * 6800, simplify.
