solve for a
c = 8 π a b
a. 8 π b c = a
b. c/8 π = a
c. c/8 π b = a
d. c/8 = a

Option C.

Step-by-step explanation:

The given expression is c = 8πab

We have to solve this for the value of a

Dividing the expression by 8πb on both the sides.

Therefore, Option C. will be the answer.

what "following statement"?

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
