c= 12.19

Step-by-step explanation:

Let's solve for c.

5.3(4x−2.3)=21.2x+c

Step 1: Flip the equation.

c+21.2x=21.2x−12.19

Step 2: Add -21.2x to both sides.

c+21.2x+−21.2x=21.2x−12.19+−21.2x

c=−12.19

c=−12.19

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
