Answer: f(x) = -3x + 4
Step-by-step explanation:
The function is represented by
9x + 3y= 12
This is a linear equation with x as the independent variable. This means that if x is the independent variable, the y is the dependent variable. The values of y depends on the values of x. In order to represent the function, 9x + 3y= 12, we would rearrange the function such that y stands alone on the left hand side of the equation. This becomes
9x + 3y= 12
Subtracting 9x from both sides,
9x -9x + 3y = 12 - 9x
3y = 12-9x
Dividing the lefthand side and right hand side of the equation by 3, it becomes
3y/3 = (12-9x)/3
y= -3x + 4
using function notation,
y = f(x) = -3x + 4
Answer:
X=2
I really hope this helps!
To write and equation we call y=oil and x=vinager, so:
To find the constant k we can use the point in the picture (vinager, oil) = (x, y) = (1, 1.5), so:
So, the equation is:
Now, the meaning of the point (1, 1.5) is for 1 amount of vinager you need 1.5 amount of oil.
