A company sells widgets. The company's fixed and variable costs are modeled by the function C(r) =0.28x +34000. Its revenue is modeled by the function R(x) 9.9r. How many widgets does the company have to sell to break even? Round your answer up to the nearest whole number, if needed.

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

answer:

c) the x-coordinate of the center of the circle increases by 3
