Step-by-step explanation:
If 3ml of water = 1 part milk
12ml of water = x
3x=12
3x/3=12/3
Cancelling out by 3
x=4
Therefore she will need 4 part milk to make the recipe.
Answer:
x = 6
Step-by-step explanation:
Given
y = 
x - 3 and y = 11, thus
x - 3 = 11 ( add 3 to both sides )
x = 14
Multiply both sides by 3 to clear the fraction
7x = 42 ( divide both sides by 7 )
x = 6
Answer:
Graph g(x) = 2x - 3
Step-by-step explanation:
Plug in (x+1) to f(x) = 2x - 5:
g(x) = 2(x+1) - 5 = 2x + 2 - 5
g(x) = 2x - 3

Answer:
(gºf)(0) is 6
Step-by-step explanation:
It is a composition of functions problem, where
(gºf) = g(f(x)) is the composition of the functions g(x) and f(x). (gºf)(0) is the composition of the functions at the point x = 0. First, we find that function that is the g composite of x, then we replace x by 0.
g(4), for example, is g when x = 4, right? So g(4) = 4.
So,
g(f(x)) is going to represent g when x = f(x). x = f(x) when x = 2x + 6, so:
g(f(x)) = g(2x+6) = 2x + 6
We have that
g(f(x)) = gºf(x) = 2x + 6
Now, we just have to find the value of the function at x = 0. So
gºf(0) = 2(0) + 6 = 0 + 6 = 6.
(gºf)(0) is 6
