Answer:
Expand the 21(2-x)=42-21x
then you add 12 x with 42-21x
making it 42-9x=44
hence,
-9x= 2
9x= -2
x= - 2/9
hope this helps. :)
Answer:
Step-by-step explanation:
9 3/10. 5/10+5/10 is 1. 8 3/10+ 1 is 9 3/10
I assume the equation described is:
( x + 6 ) / ( x^2 - 64 )
You can compare the degree of the numerator and denominator in a function that takes the form of this type of rational equation.
Here are the three rules
#1 (Correct Answer): When the degree of the numerator is smaller then the denominator the horizontal asymptote is y = 0
#2 If the degree of the numerator and denominator is the same, then you take the leading coefficient of the numerator (n) and denominator (d) to create the answer y = n / d in this equations case it would be 1 / 1 since variables technically have an invisible 1 in front of them since anything multiplied by 1 is its self, 1x = x
#3 When the degree of the numerator is greater then the degree of the denominator then this means that it does not have a horizontal asymptote.
Again the final answer is that the horizontal asymptote is y = 0
