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
Model rule is: (+)(-)= -
and the product is -520
You just have to sum the 32 invited fleas to the 16 that were there previously.
32 + 16 = 48
The discontinuity are the point wherein the function is not defined.
The zeros are the points wherein f(x)=0.
Computing the discontinuity points:
Set

then the discontinuity point is at

.
Comptine the zeroes:
Set

Compute the discriminant:

Then with quadratic formula we get the solutions:

The two zeros are
