Answer:
c
Step-by-step explanation:
x^2+5x-14
factor by finding multiples of (-14) that add up to 5
7*-2=-14
7+-2=5
So the factored out equation is (x+7)(x-2)
Therefore the solutions are x=-7 and x=2
Answer:
5.4

Juss took the test
Answer:
The second option will cost her less than the first one.
Step-by-step explanation:
In order to solve this problem we will create two functions to represent the cost of the car in function of the miles drove by her.
For the first option we have:

For the second option we have:

Since she intends to drive it for 10,000 miles per year for 6 years, then the total mileage she intends to drive her car is 60,000 miles. Applying this to the formula of each car and we have:


The second option will cost her less than the first one.
Check the picture attached.
Let OB be the radius of circle with center O.
Let B' be the image of B after the described rotation
OB and OB' are sides of the equilateral triangle OBB'.
The x coordinate of B' is the midpoint of OB, that is 5.
In the right triangle B', point (5, 0) and B:
Distance point (5, 0) to B is 5
|B'B|=|OB|=10
so by the pythagorean theorem:

units
