Consider the function represented by the equation y minus 6 x minus 9 = 0. Which answer shows the equation written in function n
otation with x as the independent variable?
f of x = 6 x + 9
f of x = one-sixth x + three-halves
f of y = 6 y + 9
f of y = one-sixth y + three-halves
2 answers:
Answer: First option.
Step-by-step explanation:
You know that the function represented by the equation is the following:

Then, you can follow these steps in order write the equation in function notation with "x" as the independent variable:
1. Solve for "y":
Add
to both sides:

Add 9 to both sides:

2. Since
is a common way of representing "y", you get:

Answer:
a) f(x) = 6x+9

Not sure about a-1, hope I helped.
Step-by-step explanation:
Given
5x + 2x + 2 = 9x + 4
9x - 5x - 2x = 2 - 4
9x - 7x = - 2
2x = - 2
x = - 2 / 2
Therefore x = -1.
Answer:
$18.75
Step-by-step explanation:
Let
y = Total cost
x = number of kilometers
The equation:
y = 3.75 + 1.50x
If x = 10 km
y = 3.75 + 1.50(10)
= 3.75 + 15
= 18.75
y = $18.75
y = Total cost = $18.75
