Answer:
B. No solutions
Step-by-step explanation:
The equations describe lines with the same slope but different y-intercepts. They are parallel, so cannot intersect.
There are no solutions.
Answer:
n=5/3
Step-by-step explanation:

simplified it would be 5/3
(If you wouldn't mind, if this helped you, please give brainliest, I'm trying to get an achievement)
The pyhtagorean states that to find c, use the eqaution,

.
Substitute 1 for a and 20 for b;
c^2=1+400
c^2=401
c=
which is about 20.02
Hope this helps.
Answer:
2.25 radians
Step-by-step explanation:
First we need to find the length of the circunference, using the formula:
C = 2 * pi * r
Where r is the radius. Using r = 8, we have:
C = 2 * pi * 8 = 50.2655 cm
Now, to find the measure of the central angle related to that arc of 18 cm, we can use a rule of three, knowing that the whole circunference has a central angle of 2pi radians:
2pi rad -> 50.2655 cm
x -> 18 cm
x = 18 * 2pi / 50.2655
x = 2.25 rad
The answer is x-4=9 because it is 4 LESS than a number that equals 9. x would equal 9+4 which is 13.
