Can i please get some help on this?
puteri [66]

Answer:

b

Step-by-step explanation:

The slope of b is 5.5 whereas the slope for the other three graphs are 5, so B is different from the rest.

A. (4, 0.8), so by rise over run, the slope is 4/0.8=5.

B. (55, 10), so 55/10=5.5.

C. (20, 4), so 20/4=5.

D. (50, 10), so 50/10=5.

Since B is the only graph with a slope of 5.5 and the other graphs have a slope of 5, the answer is B.

The function f(x) varies inversely with x and f(x)=8 when x=3
Sedaia [141]

Answer:

12

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form y*x=k or y=k/x

In this problem we have

For x=3 -----> f(x)=8

so

Find the value of k

f(x)*x=k

substitute the value of x and f(x)

8*3=k

k=24

therefore

the equation is equal to

f(x)=24/x

For x=2 -------> substitute in the equation and find the value of f(x)

f(x)=24/2=12
