Answer:
Step-by-step explanation:
Slope of line is 2.
Any perpendicular to the line has slope -½
since you're starting with 745 thats your first number and your deleting 25 pitures everyday so your equation would be
745 - 25x
Answer: First Option
Step-by-step explanation:
Quadratic quadratic functions have the following form:
Where the point (h, k) is the vertex of the function.
For a quadratic function of the form the vertex of the function is at the point
In this case the function is:
Then:
The vertex is:
Note that
Therefore the vertex is the point
Finally we have that
The function in vertex form is :
Answer:
After 0.4 miles the Unlimited Mileage Plan is a better deal.
Daily Mileages > 0.4
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
First we can create a Formula to calculate the price of each plan, like so...
Unlimited Mileage: 50x = Total
Per mile: 40x + 25y = Total
- X being the days rented
- Y being amount of miles
Since we want to calculate at what daily mileage the unlimited plan becomes better than the regular, we can substitute x for 1 and equal both plans together. Then solve for the minimum amount of miles in which the prices meet.
...subtract 40 on both sides
.... divide both sides by 25
Now we can see that at 0.4 miles both prices are the same. This means that after 0.4 miles the Unlimited Mileage Plan is a better deal.
