We have been given two functions f(x)=-8x^3+5x^2+7x+4 and g(x)=8x^3-2x+3. We are asked to find (f+g)(x).

We will use composite function property (f+g)(x)=f(x)+g(x) to solve our given problem.

(f+g)(x)=-8x^3+5x^2+7x+4+8x^3-2x+3  

Now we will combine like terms as:

(f+g)(x)=-8x^3+8x^3+5x^2+7x-2x+4+3

(f+g)(x)=5x^2+5x+7

Therefore, the value of  (f+g)(x) would be 5x^2+5x+7.

\frac{df+10}{6}= g

Now, multiply both sides by 6 and you get.....

 df+10=6g

now, subtract 10 on both sides and you get.....

df=6g-10

now divide both sides by d to get f by itself and you get........

f= \frac{6g-10}{d}

Galina-37 [17]

Answer:

B

Step-by-step explanation:

A proportional relationship is represented by linear function with its linear parameter "b" equal to zero. Since b is equal to zero, the line passes through the origin and the function/relation is proportional.

To verify that we divide the y coordinate over the x coordinate we obtain a constant called k, which is the slope.

For instance:

y=2x

According to this function we can easily check a proportional relationship among its points:

(1,2), (2,4), (4,8), (6,12), ...

k=\frac{y}{x}=\frac{2}{1}=\frac{4}{2}=\frac{12}{6}\Rightarrow k=2
