Parallel: 1/4
The <em>correct answer</em> is:
|w-20| ≤ 0.12.
Explanation:
We first find the average of the two ends of the inequality:
(19.88+20.12)/2 = 40/2 = 20
This will be the number subtracted from w in the inequality.
Now we find the difference between this value and the ends:
20-19.88 = 0.12
20.12 - 20 = 0.12
This will be what our absolute value inequality ends with; the "answer" part, so to speak.
Since this inequality is written in compact form, it must be an "and" inequality; this means the absolute value inequality must be a "less than or equal to."
This gives us
|w-20| ≤ 0.12
For this equation I would assume you use substitution, you plug in what y equals (3x -2), for the y in the second equation (4x - 4y = 8), you now have 4x - 4(3x-2) = -8 you then proceed to factor out this equation, you distribute the -4 and now you have 4x -12x + 8 = -8 you then subtract the -12x from the 4x and the result is -8x + 8 = -8, you then proceed to isolate the x subtracting the 8 from both sides and you now have -8x =-16 you then isolate the x by dividing -8 from both sides, your results are x = 2, you answer isn’t negative 2 because when you divide two negatives they cancel out creating a positive number.
