Suppose a varies directly as b and inversely as c. Find b when a = 5 and 4, if b = 12 when C3 and a = 96

The value of b is 5/6

Step-by-step explanation:

The relationship stated as "a varies directly as b and inversely as c" can be written as:

Where k is the constant of proportionality. We need to find its value by plugging in the given condition: b=12 when c=3 and a=96:

Solving for k:

The relation is now written as:

Now we find the value of b when a=5 and c=4. Solving for b:

The value of b is 5/6

60

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
