It is b: False 1,729 isn’t divisible by 9
Answer:
a = π n for n element Z
Step-by-step explanation:
Solve for a:
sec(a) + tan(a) = sec(a) - tan(a)
Subtract sec(a) - tan(a) from both sides:
2 tan(a) = 0
Divide both sides by 2:
tan(a) = 0
Take the inverse tangent of both sides:
Answer: a = π n for n element Z
Answer:
x={-3/2,-13/2}
Step-by-step explanation:
3-2|x+4|+3=1
-2|x+4|+6=1
-2|x+4|=-5
|x+4|=5/2
x+4=5/2
x+4=-5/2
x=5/2-4
x=-3/2
x=-5/2-4
x=-13/2
Which of the following relations represent a function? A. {(-1,-1),(0,0),(2,2),(5,5)}. B. None of these. C. {(0,3),(0,-3),(-3,0)
Cerrena [4.2K]
Answer:
A
Step-by-step explanation:
In a list of ordered pairs, a relation that is a function will not have any repeated x-values.
A -- a function (x-values are {-1, 0, 2, 5} with no repeats)
B -- irrelevant
C -- not a function (x-values are {0, 0, -3, 3} with 0 being repeated)
D -- not a function (x-values are {-2, -1, -2, 2} with -2 being repeated)
