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:
i dont speak that language l m a o
Step-by-step explanation:
First we need to calculate how fast she was going in one hour:
116 / 5.8 = 20
then multiply that by 5 to get how far she will go in 5 hours
20 * 5 = 100
5600
20000*.18= 3600
3600*4= 14400
14400- 20000= 5600
