Answer:
51. B=10 52. V=-11 53. N=18 54. X=-18 55. N=10 56. A=16 57. N=-6 58. P=11 59. X=2 60. K=16
Step-by-step explanation:
Answer: Option (3)
The slope of the given line is
Thus, the answer must be Option (3)
|b|= 4b+15
-b=4b+15
-b-4b= 15
-5b= 15
b= 15/-5
b= -3
the ans -3
Diameter = 12
Radius = 12/2 = 6
