Solve the problem by entering and solving the equation. Four less than the quotient of a number and 4 is 17. What is the number? Let n be the unknown number.
The equation is
The number is

Step-by-step explanation:

n/4 - 4 = 17

n/4 = 21

n = 84

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
