Answer:
1/3x - 3
Step-by-step explanation:
To find the inverse, we exchange x and y and then solve for y
y =3x+9
Exchange x and y
x = 3y+9
Then solve for y
Subtract 9 from each side
x-9 =3y+9-9
x-9 = 3y
Divide by 3
1/3(x-9) = 3y/3
1/3(x-9) = y
Distribute
1/3x-3 = y
The inverse is 1/3 x -3
Well, you can do
area=legnth times widht
perimiter=2(legnth+width)
then you just subsitute x for legnth and y for width then solve
area=xy
perimiter=2(x+y)
then graph and find the intersection to find the solution
Step-by-step explanation:

Answer: =4 2/3
Step-by-step explanation:
Point slope form:
we need a point (x₀,y₀) and the slope (m).
y-y₀=m(x-x₀)
In this case:
m=3
(5,19)
y-19=3(x-5)
y-19=3x-15
y=3x-15+19
y=3x+4
Answer: y=3x+4
