Answer:
<h2>
D. y = cot x</h2>
look at the picture.
cot(x) not exist for x = kπ, k∈Z
(vertical asymptotes ...,-2π, -π, 0, π, 2π, ...)
tan(x) not exist for x = π/2 + kπ, k∈Z
(vertical asymptotes ...,-3π/2, -π/2, π/2, 3π/2, ...)
csc(x) not exist for x = kπ, k∈Z
(vertical asymptotes ...,-2π, -π, 0, π, 2π, ...)
cos(x) exist for any value of x
Answer:
3.666666667 + 2.333333333y
Step-by-step explanation:
Simplifying
3x + -7y = 11
Solving
3x + -7y = 11
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7y' to each side of the equation.
3x + -7y + 7y = 11 + 7y
Combine like terms: -7y + 7y = 0
3x + 0 = 11 + 7y
3x = 11 + 7y
Divide each side by '3'.
x = 3.666666667 + 2.333333333y
At most, 20. 20 is the greatest common factor of all numbers.
