X = (12 +- sqrt (144 -4(7)(3))/14
x = (12 + - sqrt (144 - 84))/14
x = (12 + - sqrt(60))/14
x = (12 + - 2sqrt 15))/14
x = (6 + - sqrt 15) / 7

Choose the quadrants on a coordinate plane which represent the location of an (x;y) pair satisfying the following equation: |x|+
Sergio [31]

Answer:

On any quadrant you choose the points each will always be positive

Step-by-step explanation:

The absolute value of a negative number is positive  and the same goes for a positive number (the absolute value will always be positive) because it is how many numbers it is away from 0. For Example; the absolute value of -4 is +4 because it is 4 numbers away from 0. If |x|+|y| = |x+y| then an example would be |-4| + |3| = |-4+3| it would be 7 because the |-4| is 4 and the |3| is 3 giving you the sum of 7

Hope this helps

-2z = 6
z = -3
