ruslelena [56]

F= -1 2/3 or 5/3

In order to find the answer all you have to do is multiply both sides by -4/3.

-3/4f × -4/3 = f

-4/3 × 5/4 = -20/12

-20/12 simplified is -5/3 or -1 2/3

The graph shown here is the graph of which of the following rational
IrinaK [193]

Answer:

Option (B)

Step-by-step explanation:

From the graph attached,

Vertical asymptotes of the function are x = -2, 5

Horizontal asymptote is y = 0

Now we take each option,

Option (A),

F(x) = \frac{x(x-5)}{(x+2)}

No horizontal asymptote

Vertical asymptote : x = -2

Option (B),

F(x) = \frac{x}{(x+2)(x-5)}

Horizontal asymptotes : y = 0

Vertical asymptotes : x = 5, -2  

Option (C),

F(x) = \frac{(x+2)(x-5)}{x}

Vertical asymptote : x = 0

No horizontal asymptote.

Therefore, Function given in Option (B) matches the asymptotes given in the graph.

Option (B) represents the graph.

Total cup cakes c

Set up propportion:

12/30=c/100
30c=(12)(100)
