What is the inverse of the function below?
f(x)=x-7/3
a.) f^-1(x)=-x+7/3
b.) f^-1(x)=3/x-7
c.) f^-1(x)=x-7
d.) f^-1(x)=3x+7

f^-1(x)=3x+7

Step-by-step explanation:

according to mathaway .com / algebra this is the correct answer. I do not have the expanded view and I did get it correct on my test so this is the correct answer.

is it 35

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
