It is quantitive and from that, I'm pretty sure it's discreet, sorry if the second part isn't very helpful.
1 real solution means that it has a multiplicity aka
if r is the solution
0=(x-r)^m
theone that fits that is B, the solution is x=3
B is answer
Answer:
What is the question?
Step-by-step explanation:
Let the two numbers be x and y.
x + y = 86
+
x - y = 12
_________
2x + 0 = 98
__________
2x = 98
x = 98/2
x = 49
From x + y = 86
49 + y = 86
y = 86 - 49
y = 37
The numbers are 49 and 37.
The cos y = 0.3. The cosine of any angle is the same as the sin of the complement of the same angle.
