Add like terms. Like terms are terms that have the same variable.
<span>9x + 2y + 6 + 9y + 7 =
= 9x + 2y + 9y + 6 + 7
= 9x + 11y + 13
The coefficient of y is 11.
The constant is 13.

Answer:
y=0
Step-by-step explanation:
Hello!
To solve this problem and find the asymptote you must find the value of x, for which F (x) (or y) becomes infinite, for this we solve the equation for X
As you can see if Y takes a value of zero, then X would tend to be an infinitely large value so we conclude the horizontal asymptote is y = 0, I also attached the graph!
Arccos(cos 7pi/2)
cos 7pi/2 = cos 630 = cos (630-360) = cos 270 = 0
arccos(0) = 90 since cos 90 = cos 270
(x): 0 - 30 - 45 - 60 - 90
sin (x) 0 - 1/2 - 1/2 √3 - 1/2 √3 - 1
cos (x) 1 - 1/2 √3 - 1/2 √3 - 1/2 - 0
tan (x) 0 - 1/√3 - 1 - √3 - ∞
Rules for sin cos tan value in each quadrant :
quadrant = I(0-90) - II (90-180)- III(180-270) - IV(270-360)
sin (x) = positive- positive - negative - negative
cos (x) = positive- negative- negative - positive
tan (x) = positive- negative- positive - negative
The division between two numbers is positive if and only if they have the same sign. So, this fraction is positive if numerator and denominator are either both positive or both negative.
For this reason, you want to study the sign of numerator and denominator separately first.
As for the numerator, you have
Similarly, for the denominator you have
(note that we used strict inequality for the denominator, since it can't be zero).
So, the sign of the fraction works like this:
- If both numerator and denominator are negative (or, at most, the numerator is zero if ), so the ratio is greater than or equal to zero.
- If the numerator is positive and the denominator is negative (or, at most, the numerator is zero if ), so the ratio is less than or equal to zero.
- If both numerator and denominator are positive, so the ratio is greater than or equal to zero.
