Answer:
a). (5,30) (0,20)
b). (40,130) (35,120)
Step-by-step explanation:
a). (5,30) (0,20)
solid red line's solutions are all going to be going down and dashed blue line's solutions will be going up all solutions in those regions are considered solutions
b). (40,130) (35,120)
points are non-solutions because they are not in the shaded region for either line's solution .
haven't done this in a hot minute so im not sure 100%
The binary number for 26 is 11010
The rule, letting d=discriminant:
d>0, two real solutions
d=0, one real solution
d<0, no real solution (but there are two imaginary solutions)
So if it has only one real solution, the discriminant is equal to zero.
