** x + 5 = 7
x = 2
** x + 5 = 9
x = 4
{2,4}
So discriminant is being counted from that equation:
b^2-4ac = 36-36 = 0
As discriminant is 0, then there is just 1 root -> -b/2a = 6/2 = 3.
The equation of the vertical line passing through point -4,7 would be X = -4.
Answer:
4
Step-by-step explanation:
first you simplify, so -1-3=-4.
|-4|
the absolute value of negative four is just four with all signs removed (in this case, negative sign)
4
