Answer:

k = 11.87

Step-by-step explanation:

Because the two expressions should be equivalent, set the two expressions equal to each other.

-10.5x+k=-2.1(5x-3.7)+4.1

Begin simplifying the equation and solve for k.

-10.5x+k=-10.5x+7.77+4.1 (distributive property)

-10.5x+k=-10.5x+11.87 (combine like terms - 7.77 + 4.1)

k = 11.87 (add 10.5x to both sides to combine like terms -- the x values cancel out because -10.5x+10.5x = 0.  Therefore, you are left with k = 11.87)

17) f(x) = 16/(13-x).

In order to find domain, we need to set denominator expression equal to 0 and solve for x.

And that would be excluded value of domain.

13-x =0

Adding x on both sides, we get

13-x +x = x.

13=x.

Therefore, domain is All real numbers except 13.



18).f(x) = (x-4)(x+9)/(x^2-1).

In order to find the vertical asymptote, set denominator equal to 0 and solve for x.

x^2 -1 = 0

x^2 -1^2 = 0.

Factoring out

(x-1)(x+1) =0.

x-1=0 and x+1 =0.

x=1 and x=-1.

Therefore, Vertical asymptote would be

x=1 and x=-1

19) f(x) = (7x^2-3x-9)/(2x^2-4x+5)

We have degrees of numberator and denominator are same.

Therefore, Horizontal asymptote is the fraction of leading coefficents.

That is 7/2.


20) f(x)=(x^2+3x-2)/(x-2).

The degree of numerator is 2 and degree of denominator is 1.

2>1.

Degree of numerator >  degree of denominator .

Therefore, there would no any Horizontal asymptote.
