what is inverse function of f(x) = -3x+27
Answer:
y=9-x/3
Step-by-step explanation:
swap the variable y=27-3x becomes x=27-3y
now solve the equation x=27-3y for Y
y=9 - x/3
and done:)

Slove the system of equations by useing the substitution method. 2x - 3y=9 y=x-4
Answer:
x = 3
y = -1
Step-by-step explanation:
in this system, we are given that y = x - 4
this means that we can take the other equation and replace y with x - 4:
so 2x - 3y=9 turns into
2x -3 (x - 4) = 9
distribute -3 to x and -4:
2x - 3x + 12 = 9
add like terms and subtract 12 from both sides
-x = -3
divide both sides by -1 to get rid of the negative on x:
x = 3
now we have the value of x, so we can replace the x in y = x - 4 with the value we just got
so y = x- 4 turns into
y = (3) - 4
solve and you get
y = -1

Two large and 1 small pump can fill a swimming pool in 4 hours. One large and 3 small pumps can also fill the same swimming pool in 4 hours. How many hours will it take 4 large and 4 small pumps to fill the swimming pool? Please help me answer I'm in 5th grade and this is so hard.
Answer:
Let's define.
L = rate at which the large pump fills the pool.
S = rate at which the small pump can fill the pool.
We have two relations:
"Two large and 1 small pump can fill a swimming pool in 4 hours."
(2*L + S)*4h = 1
"One large and 3 small pumps can also fill the same swimming pool in 4 hours."
(L + 3*S)4h = 1
Then we have the system of equations:
(2*L + S)*4h = 1
(L + 3*S)4h = 1
To solve this system, we need to isolate one of the variables in one of the equations, i will isolate S in the first equation:
S = 1/4h - 2*L
Now we can replace that in the second equation:
(L + 3*(1/4h - 2*L))4h = 1
L + (3/4h) - 6*L = 1/4h
-5*L = 1/4h - 3/4h = -2/4h
L = (2/4h)*(1/5) = (2/20h) = 1/10h
This means that one large pump needs 10 hours to fill one pool.
With this, we can find the value of S:
S = 1/4h - 2*L = 1/4h - 2/10h = 5/20h - 4/20h = 1/20h
This means that a small pump needs 20 hours to fill a pool.
Now we can answer:
How many hours will it take 4 large and 4 small pumps to fill the swimming pool?
We need to solve the equation:
(4*(1/10h) + 4*(1/20h))*T = 1
We need to find the value of T.
T = 1/((4*(1/10h) + 4*(1/20h)) = 1.67 hours.
This means that 4 large and 4 small pumps need 1.67 hours to fill a pool.
