Find an equation for the inverse of the relation
17.) y=4x
19.) y=3x+1

17.) y= x/4

19.) y= (x-1)/3

Step-by-step explanation:

switch the x and y in both equations, so your equations should look like this:

17.) x= 4y

19.) x= 3y+1

17.) divide the 4 on both sides and your equation would be:

y= x/4

19.) subtract the 1:

x+1 = 3y

divide the 3:

y= (x-1)/3

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

40 x 50 = 2000
