X=19 y=7 I think
because 26-12=14 divide 2 =7 so 12+7=19
19=fiction
7=non fic
Answer:
Step-by-step explanation:
Part A : when comparing graphs : A system of equations will have no solutions (on a graph) when your lines never cross each other. They never cross each other because your lines are parallel.
Part B : by comparing each algebraic equation : A system of equations will have no solution if your lines are parallel. Parallel lines will have the same slope but different y intercepts. Example :
2x - y = 2
4x - 2y = 8
put both equations in slope intercept form
y = 2x - 2
y = 2x - 4
they both have the same slope of 2.....and the y intercepts are different....meaning they are parallel lines and have no solutions
For this case we have that by definition, the discriminant of a quadratic equation , is given by:
: Two different real roots
: Two equal real roots
: Two different complex roots
If we have , then:
Substituting the values:
Thus, we have two equal real roots.
ANswer:
We have two equal real roots.
