B.
For all 3 to work together, they can paint 1 room per hour.
C.
John can paint a room at 1/4 of a room per hour.
Rick can paint a room at 1/5 of a room per hour.
Together they can paint a room at a rate of 9/20 of rooms per hour.
D.
1 = 1/4j + 1/5r + 11/20m (john, rick, molli)
E.
The least common denominator is 20
F.
1 = 1/4(0) + 1/5(0) + 11/20x
1 = 0 + 0 + 11/20x
1 = 11/20x
x = 1/(11/20)
x = 1 9/11
It will take Molli 1 hour and 49 minutes (60 x 9/11) to paint the room alone.
Answer:
Option (B)
Step-by-step explanation:
From the graph attached,
There are two functions graphed,
y = f(x) and y = h(x)
h(1) = 0 [Output value of function 'h' at the input value x = 1]
Since, g[h(1)] = g(0)
Therefore, value of function 'h' (output value) at (input value) x = 0,
g(0) = -5
Option B will be the correct option.
Answer:
-27
Step-by-step explanation:
f(a) = -3a + 3
f(10) = -3(10) + 3
= -30 + 3
= -27
We have to find the domain of the given function
"The domain of a function is the set of input or argument values for which the function is real and defined"
Now, we have to find the values of 'x' for which the given function will be real and defined.
As we can observe that for any real number, the given function will be real and defined.
Therefore, the domain of the given function is 
or
.
Or we can say that the domain of the given function is the set of all real numbers.
