Answer:

c. y=-\frac{2}{3}x+6

Step-by-step explanation:

We have to choose that equation which represents the given graph.

From given graph , the graph cut the y- axis at point (0,6) and cut the x- axis (9,0).

a.y=-2x-6

Substitute x=0 then we get

y=-6

But we have y-intercept y=6

Therefore, this equation does not represents the given graph.

b. y=\frac{2}{3}x+6

Substitute  y=0 then, we get

\frac{2}{3}x+6=0

\frac{2}{3}x=-6

x=\frac{-6\times 3}{2}=-9

The x- intercept =-9

But , we have x=9

Therefore, it is false.

c. y=-\frac{2}{3}x+6

Substitute x=0 then we get

y=6

Substitute y=0

Then, we get

-\frac{2}{3}x+6=0

\frac{2}{3}x=6

x=\frac{6\times 3}{2}=9

Hence, the line passing through the point (9,0) and (0,6) .Therefore, it represents the given graph.

Answer:c. y=-\frac{2}{3}x+6

Simplify f+g / f-g when f(x)= x-4 / x+9 and g(x)= x-9 / x+4
steposvetlana [31]

f(x)=\dfrac{x-4}{x+9};\ g(x)=\dfrac{x-9}{x+4}\\\\f(x)+g(x)=\dfrac{x-4}{x+9}+\dfrac{x-9}{x+4}=\dfrac{(x-4)(x+4)+(x-9)(x+9)}{(x+9)(x+4)}\\\\\text{use}\ a^2-b^2=(a-b)(a+b)\\\\=\dfrac{x^2-4^2+x^2-9^2}{(x+9)(x+4)}=\dfrac{2x^2-16-81}{(x+9)(x+4)}=\dfrac{2x^2-97}{(x+9)(x+4)}\\\\f(x)-g(x)=\dfrac{x-4}{x+9}-\dfrac{x-9}{x+4}=\dfrac{(x-4)(x+4)-(x-9)(x+9)}{(x+9)(x+4)}\\\\\text{use}\ a^2-b^2=(a-b)(a+b)\\\\=\dfrac{x^2-4^2-(x^2-9^2)}{(x+9)(x+4)}=\dfrac{x^2-16-x^2+81}{(x+9)(x+4)}=\dfrac{65}{(x+9)(x+4)}


\dfrac{f+g}{f-g}=(f+g):(f-g)=\dfrac{2x^2-97}{(x+9)(x+4)}:\dfrac{65}{(x+9)(x+4)}\\\\=\dfrac{2x^2-97}{(x+9)(x+4)}\cdot\dfrac{(x+9)(x+4)}{65}\\\\Answer:\ \boxed{\dfrac{f+g}{f-g}=\dfrac{2x^2-97}{65}}
