Answer:
The equation of the parabola in vertex form is .
Step-by-step explanation:
Since the directrix is of the , then the equation of the parabola in vertex form is of the form:
(1)
Where:
- Dependent variable.
- Independent variable.
- Least distance between focus and directrix.
, - Coordinate of the vertex.
The least distance between focus and directrix is determined by Pythagorean Theorem:
Now, we determine the location of the vertex by the following vectorial formula:
(2)
If we know that and , then the location of the vertex is:
And the equation of the parabola in vertex form is .
The answer would be:
C=12x-1
x being the amount of hours Carey is working.
c being the amount she is getting paid.
The reason why it is 12 is because Anderson is only getting paid $6 per hour, which is half minus 1 per hour Carey is getting paid.
So, by doubling the amount of what Anderson is getting paid minus 1, multiplied by the amount of hours she is working, you should get the correct answer.

Distribute the .15 on the right side to get:
20 + .5x + 3 + .075x
Then, combine like terms (add numbers together and add x terms together):
.575x + 23
...and that's your final answer!
